Wikia Search, the Web search engine from Wikia, Inc. has been having recurring problems with their website since 2 p.m. EST on Monday (December 1).
One third of the requests to the website result in a HTTP 503 server error message (service unavailable). See screenshot below.

Since the problems started on Monday, the website has been unavailable for a total of more than 14 hours. The graphs below show the hourly average uptime percentage for the Wikia Search website.
Here is one for the last 36 hours, showing an hourly uptime hovering around 65%.

When looking at the last seven days, it’s easy to see when the problems started, and that they started after a longer period of stability.

Even when the Wikia Search website loads, it doesn’t always load correctly. We tried reloading their web page manually several times, with varied results. Sometimes it loaded fine, sometimes it seems like style sheets weren’t loaded, etc.
With almost two days with this problem, hopefully Wikia is on their way to finding a solution to whatever problem it is that they are having with Wikia Search.
The data above comes from the Pingdom uptime monitoring service.
UPDATE:
The Wikia Search website started working properly again after 2 p.m. EST on December 3. The total accumulated downtime for this incident ended up being 16 hours.

Wordpress.com, the popular blogging service from Automattic, has some interesting growth statistics posted on its website. Among other things, there is a graph showing how many new blogs are created on the service each day.
Based on the graphs that Automattic provides us with, it’s actually not that difficult to estimate how much Wordpress.com will grow in 2009. Which, of course, was a temptation we couldn’t resist!

Operating systems on supercomputers used to be custom-made affairs, but this has changed. These days, Linux has become a popular choice for supercomputers. But how popular? You may be surprised.
Top500.org maintains a list of the fastest supercomputers in the world. A new list was published yesterday (it happens twice a year), so we took the opportunity to go through the list and find out what OS the top 20 supercomputers are using.
It took some work, but the results are interesting.

I’m surprised a rep hasn’t issued a statement anywhere about this issue.
