Pingdom: The major incidents on the Internet in 2010

In what has become something of a yearly tradition, it’s now time for us to present 10 of the most noteworthy incidents on the Internet from this past year. As you’ll see, 2010 has been very interesting.

Just like previous years, we have included problems ranging from website outages and service issues to large-scale network interruptions. If you’re an avid Web user, you are bound to recognize several of them.

Let’s get started! The major incidents on the Internet in 2010 were…

Wikipedia’s failover fail

Wikipedia has become so ubiquitous that it can’t go down for a minute without people noticing. According to Google Trends for Websites, the site has roughly 50 million visitors per day.

In March, when servers in Wikimedia’s European data center overheated and shut down, the service was supposed to fail over to a US data center. Unfortunately, the failover mechanism didn’t work properly and broke the DNS lookups for all of Wikipedia. This effectively rendered the site unreachable worldwide. It took several hours before everyone could access the site again.’s big-blog crash got a pretty bad start this year when a network issue caused the biggest outage the service had seen in four years. The outage became extra noticeable not just because of the sheer number of blogs it hosts (at the time 10 million, now many more), but also because so many high-profile blogs use it. The outage took down blogs such as TechCrunch, GigaOM and the Wired blogs for almost two hours in February.
