Top 6 Tools for DNS Troubleshooting
Troubleshooting never ends. Problems in network computing can happen at many different levels. One technology that every internet user depends on is DNS, which stands for domain name system. A domain name is an alphanumeric designation for an IP address. DNS servers are the databases that manage the hierarchical domain name system. Sometimes these servers are not configured properly. That’s where the DNS troubleshooting comes it.read more
What Went Down in 2017
The internet is replete with Top Ten lists and other rankings. But the criteria for distinguishing between #1 and #10 is often no more than personal whim. So with the caveat that these are not necessarily the worst or the biggest, we’ve decided to list and describe some of the most interesting outages in the world of cyberspace in 2017.read more
Why Ransomware is a Threat to Availability
Ransomware has vividly shown how truly devastating a ransomware attack can be upon businesses and organizations that rely on an omnipresent connection with their customers, users and partners. This is why high availability and disaster recovery solutions are so imperative today. A ransomware attack is indeed a disaster that can take an organization offline and out of commission.read more
The Advantages of Software Defined Storage
Companies across the globe are rapidly undergoing a digital transformation covering every aspect of their respected organizations, especially the enterprise. This macro process has pushed IT leaders to migrate applications and data to the cloud as well as software defining their own on premise infrastructures. This is being accomplished by incorporating the technology triad of software defined compute (SDC), software defined networking (SDN) and software defined storage (SDS)read more
Does the Cloud have a Layer 1 or Layer 2?
The focus has changed in recent years from ensuring connectivity to maintaining the availability of our applications. Since these virtual machines now reside in the higher layers of the OSI model, they can be maintained through software defined networking and other cutting-edge technologiesread more
Hybrid Cloud. Hybrid IT. Hybrid Availability.
There is a lot of talk about hybrid these days when it comes to IT. For the past five years or so, the Hybrid Cloud has been a hot topic as organizations are now open to hosting their digital services and data beyond the walls of the datacenter perimeter. Recently, the new approach of managing IT within the enterprise, called Hybrid IT, has come to the forefront.read more
Load Balancing Moves to the Cloud
Everyone in the IT business has heard of load balancing, but many don’t know much about it. Even technology professionals who are familiar with the concept may know little about how it works. A brief introduction to the subject of load balancing and its development will help to round out our IT education.read more
Top Tools for Network Troubleshooting
If you are a network administrator, you really want to get a handle on your network. But even laymen sometimes need to figure out what’s going on. There are some basic tools that will help you do that. Let’s have a look at some simple pieces of software that can be accessed from nearly any workstation.read more
Minimize risk. Maximize availability.
Businesses take risks. It comes with the territory. But that doesn’t mean that an enterprise should push blindly forward, ignoring the potential threats to availability and ultimately its success. Risk assessment is essential to understanding the territory and blazing the trail ahead. And risk mitigation is the key to controlling those factors that endanger IT uptime. It all starts with a framework.read more
Root Cause Analysis to Maintain Uptime
Root cause analysis is an excellent tool for keeping your IT infrastructure healthy. You may need some in-depth troubleshooting to correct an ongoing issue. Or you may be tasked to do a postmortem on a problem that is already resolved. RCA is also a very good approach for dealing with intermittent issues. Whatever the situation, root cause analysis can be your best friend if you are trying to keep an IT service up and running well.read more
Server Hardening for Security and Availability
Server hardening is a necessary process. And it’s a never-ending one. From the moment you pull the machine out of the box (or create it in the virtual environment), it pays to be thinking about security. But server hardening can do more than keep your machine safe. It will help with performance, and it can even play a part in keeping your machine online and available.read more
Decrease Downtime with Change Management
Service providers do everything they know how to avoid downtime. Generally the best practice is not to touch a live network. If it ain’t broke, don’t fix it. But change is inevitable, and eventually every network or system will need improvements. The trick is to handle these changes with little to no disruption of running services. That’s the purpose of change management.read more
The Coming Revolution of Software Defined Networking
In the coming years, SDN will revolutionize the enterprise to the same extent that software defined computing did. In an article dated August 2, 2012, Forbes Magazine stated. “SDN holds the promise to impact the global economy to a greater degree than any other development including the browser.”read more
Why You Need a Web Application Firewall (WAF)
One of the mantras for today’s enterprise could be, “living on the edge.” With the proliferation of the cloud and the digital services and mobile apps that it hosts, today’s enterprise is all about the edge. Chances are your company or organization has a web presence on the Internet thanks to Web 2.0, which gives your customers the ability to interact with your web sites and their integrated web applications that service requests. Unfortunately, it also gives hackers the ability to interact as well. According to the 2016 Verizon Data Breach Investigation Report, 40% of all data breaches involved web application attacks.read more
Does Convergence Impact Uptime?
One of the biggest trends in data center infrastructure is convergence. Actually it has been happening for some time. Equipment footprint has been getting smaller for years. Functions that used to be handled by huge dedicated machines are now accomplished by modular cards. Specialized servers, switches, routers, and other network devices have been combined into multi-service boxes. Now with the advent of virtualization and the cloud, the footprint is getting even smaller. But with higher convergence comes a significant increase in complexity. And when complexity increases, availability usually suffers.read more
Website Down? Understanding Why
“The website is down again!” That can be pretty frustrating. In the heat of the moment, most of us don’t really care why it is down -- we just want back online. But the curious user may want to know more. What could make a web server unreachable? Why do they go down in the first place? To understand more, we should start with some basics.read more
Is the TCP/IP Protocol on the way out?
It’s pretty clear that TCP/IP is an integral part of any existing IT infrastructure. That clearly includes the cloud. The internet protocol links network components across any number of technologies. Routing protocols direct internet traffic. TCP ensures transmission reliability. TCP/IP is used both internally in the cloud as well within the supporting network infrastructure that may be transparent to the cloud environment.read more
The Foundation of Networking – It’s about Availability
As we look forward to even greater advances in technology, sometimes it helps to take a look back. Many of us take for granted the connectivity that we enjoy across a wide variety of applications. Sometimes it is seamless, and other times – well, we know that improvements are on their way. But the applications we use every day are undergirded by a whole array of technologies. And when these lower levels are out of service, then nothing works.read more
How the Availability of Big Data is Transforming the World
All over the world, companies are competing with one another in the race towards digital transformation. According to a report by Gartner in 2016, one-half of all CEO’s expect their industries to be substantially or unrecognizably transformed by digital transformation. It is a recurrent digital evolutionary process of embedding technologies into nearly everything around us in order to cultivate knowledge and innovation, turning ideas into value.read more
Why You Need Cloud Based Layer 7 Load Balancing Today

One of these overlooked areas is network load balancing.read more
Making a Case for Cloud and its Disruptive Benefits
Once again, society is on the cusp of witnessing another disruptive influence that has the ability to change the course of the business world. Thankfully, the phenomenon known as “cloud” (which includes computing, infrastructure-as-a-service, software-as-a-service and much more) has few doubting its abilities to disrupt the way we conduct business today.read more
The Essence of Uptime
Uptime is a key performance indicator (KPI). Some would say it is the key performance indicator, the sine qua non, of productive computing. If you can’t keep your system operational, you have nothing. None of the many functionalities – the bells and whistles – matter one whit if your customers can’t access your site or service. The expectation in the industry is for near 100% uptime.read more
EPO: Emergency Power Off or Extremely Probable Outage?
Have you ever thought about the necessity of EPO buttons in data centers? If you think they are required by law, you are incorrect. Sadly, many believe they are, including data center designers, and they still result in outages even today. We think EPO should be an acronym for Extremely Probably Outage.read more
Enterprise DNS - Is it really that important?
Your DNS servers are probably the most critical to your network operations. Imagine you were traveling within a foreign country you had never visited before and the area was totally void of road signs or traffic directionals. Imagine you had no map or GPS navigational system to guide you. Most likely the trip would be a disaster as you would end up seeing very little of the country at all.read more
Cloud Service Level Agreement Expectations
Service Level Agreements (SLAs) are essential in the IT business. IT managers should know what to expect from their service providers. You should fully understand any SLA before signing it – especially when it comes to uptime. Everyone who has been around IT support has heard of Service Level Agreements. As we consider what is expected regarding uptime in SLAs, it might be helpful to briefly have a look at what SLAs are and their purposeread more
Downtime is no Longer Acceptable
If you went to bestbuy.com and the site was unavailable, how long would it take for you to go to amazon.com or elsewhere to find what you wanted? On average, it’s less than 30 seconds; it used to be much longer, but our society has grown impatient. If you’re not available when customers are looking for you, they will move on.read more
What is The Cloud? A Technical Explanation
The Cloud – we hear that phrase thrown around a lot. It is obviously a special place because nearly every company wants to go there, probably because we hear how wonderful everything works in the cloud. Those who go there are promised a great deal of cost savings as well. No wonder everyone is talking about it.read more
What is DNS Tunneling?
DNS tunneling is a misuse of DNS. Domain Name Servers (DNS) have been called the internet’s equivalent of a phone book. Rather than remembering an IP address with up to twelve digits, you just need to know the domain name associated with the IP address. DNS tunneling attempts to hijack the protocol to use it as a covert communications protocol or a means of data exfiltration. It is a broadly overlooked security threat.read more
Digital Realty / Telx Atlanta Power Outage
On July 12th a major power event occurred at the prominent carrier hotel at 56 Marietta Street responsible for network interconnections for a significant portion of the southeast including over 60 carriers and over 100 telecom providers.

The True Costs of Downtime for IT
Downtime is a dirty word in the IT business. Unplanned outages are unacceptable and should not be tolerated. In a universe where customers expect services to be available 99.999% of the time, any time your IT service offering is down is costly to your business. And the true cost of downtime may be more than you realize.read more
5 Ways to Increase Application Availability

Load Balancing Droplets from Digital Ocean
We recently helped a customer who had dozens of virtual machines (called Droplets) from Digital Ocean spanning multiple countries. Digital Ocean doesn’t have a load balancer, but even if they did, he was looking for a way to load balance traffic in each of 3 geographically diverse regions all without having to use DNS. He was using round-robin DNS to distribute the load among the group of servers, but it wasn’t working anywhere near the way he wanted it to, often distributing load unevenly.read more
Reroute or redirect IP traffic from one data center to another for disaster recovery
Many organizations have a business continuity or disaster recovery plan and have even implemented multi-data center redundancy with servers and other critical infrastructure at a separate location to that of their primary site. But the challenge every organization faces is how to easily and seamlessly redirect traffic from one site to another when disaster strikes.read more
Apple Suffers $32 Million Dollar DNS Outage

VPN Load Balancing and Failover with two ISPs
A common SSL or IPSEC VPN configuration scenario is one like we've shown in the (simplistic) diagram below. A corporate office has two incoming ISP connections, each with their own range of IP addresses. Clients or sites have VPN connections to the corporate office to access back-office devices in the LAN. The problem arises when the primary router or ISP goes offline. VPN tunnels that are configured using a DNS name don't fail over until DNS is updated, which is something our DNS Failover solution can nicely solve. But what about connections that rely on static IP addresses. I know Cisco ASA point-to-point VPNs require a fixed IP address, which is not uncommon amongst VPN hardware vendors. So what do you do in that case?read more
Dual WAN Link Load Balancing - for Inbound Traffic
A common inquiry we receive is whether or not any of our solutions have the capability to automate switching inbound traffic between common office WAN Internet connections, such as DSL, Cable and T1 lines.

Our Cloud is Different Than Yours
A day doesn’t go by where we are yet again annoyed with how flippant organizations are in using the word “cloud” for what appears to be a marketing hype. Take Western Digital and their My Cloud product for which I have seen many TV commercials as of late. It is simply a personal cloud storage device. What’s really “cloud” about it? Other than the fact that you can access it remotely, nothing! It gives honest, legitimate cloud providers like Total Uptime a bad rap.read more
