Addendum to the tech news item below. The recent workunit download headaches had to do with a corrupt table in the database (result) which got cleaned up during the usual weekly database outage. Of course, since there was effectively a multi-day outage over the weekend, it'll take a while to catch up. Workunits are getting pushed out as fast as we can.

Happy new year! It's been a hectic holiday season.

The air conditioner in our server closet failed a few weeks ago. The temperatures of all the systems immediately rose about 10 degrees (Celsius). Of course, this happened over a weekend, and the higher temperature values were just below warning thresholds so we didn't get alert e-mails, etc. The failure was caused by the unusual low temperatures around the Bay. Pipes froze and the air conditioner shut itself off in self-defense. We thought this was just a fluke, but a few days later it failed again. A leak in one of the pipes was discovered and fixed. We adjusted our alert system.

We had to reboot our upload server a couple times during the holidays. It randomly loses important mounts - a problem that was more chronic before SETI@home Enhanced was released (which vastly reduced the entire load on our server backend). With increased users and faster computers this is becoming a problem again. We're brainstorming about why this is happening and how to fix it.

The problems we've been having with slow queries to the result table were infrequent and temporary, but during the last few days it seems to have finally went "over the edge." We tried reducing load by removing services, restarting servers and rebooting MySQL to no avail. We're doing a table check now (during the usual weekly database backup outage). Perhaps we have a broken index. More to come as we find out what's up.

Appart for Anandtech's stats, it shows how much more/less than Anandtech.
Also shows based on Average Work Done how many days for Anandtech to overtake the team, or be overtaken by a team behind...
