Palo Alto, Calif. – Facebook was down or unreachable for
many users yesterday for around 2.5 hours, the company’s worst outage in over
four years, which it blamed on "an unfortunate handling of an error
condition." "The way to stop the feedback cycle was quite painful —
we had to stop all traffic to this database cluster, which meant turning off
the site. Once the databases had recovered and the root cause had been fixed,
we slowly allowed more people back onto the site," the company wrote in a
blog post.

"We apologize again for the site outage, and we want you to
know that we take the performance and reliability of Facebook very seriously."

Facebook’s description of the situation makes no mention of another outage yesterday
suffered by communications firm Qwest, detailed by CNET
