Global Server Load Balancing (GSLB) 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. We comment on outages that stood out (according to our own whims) and offer a larger list at the bottom that you can look at more closely on your own.
Before we begin, we should credit our sources. CloudEndure has provided a description of 7 notable outages for each quarter of 2017: Q1, Q2, Q3, Q4. CRN compiled “The 10 Biggest Cloud Outages Of 2017”. Plus we have links available for each of the outages mentioned. And of course, we scoured the internet with good ole Google to find more sources about 2017 outages. The list is not meant to be comprehensive, and someone else might come up with a much different one. That said, let’s get started — and we’ll go chronologically just to be fair.

January 26, 2017 — IBM Softlayer Issue
The Register called it a “meltdown”, and quoted a user as saying that it had been a mess ever since BlueMix took over. “Since IBM came along there have been loads of outages, planned and otherwise.” The user also said, “In the three years of service prior to this we had only one outage, in the six months after they took over we have had one outage that knocked out their AMS [Amsterdam] data center for four hours….” An IBM spokesman said the problem was due to a “planned update to extend our feature set”.
January 31, 2017 — GitLab Loses Data
Chalk this one up to human error. A company systems administrator meant to delete the backup database to make some space. Instead he deleted the primary database. One good thing about it is that the software company was given credit for being transparent about the issue.

May
May 12, 2017 — WannaCry Ransomware Hits the Web
A hack and an outage may not be the same thing, but if a hacker holds your computer for hostage so that you can’t use it, you may as well call that an outage. This hack had a pretty big impact.

November 15, 2017 — GoogleDocs Down for an Hour

November 24, 2017 — Black Friday Panic at Macy’s
