Cyber Monday saw slowdown and minor issues for several e-commerce websites. A standout was the GAP website which was completely unavailable for a total of 1 hour and 25 minutes.

Gap.com crashed at 11:37 a.m. EST, responding only with a HTTP 500 server error (internal server error).

Twenty minutes later, GAP put up a maintenance page with the words, “We’re updating our site to bring you a better shopping experience. Gap.com is temporarily closed for scheduled site improvements.” (Screenshot below.)

Almost 40 minutes later the website came back up, but only very briefly. It didn’t stabilize until 1:06 p.m. EST.

The GAP website had another outage at 10:40 p.m., lasting just 5 minutes this time.

If the standout incident on Black Friday was the Sears.com downtime, the Gap.com incident may very well have been the one for Cyber Monday.

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.
