It's been a good run.
We spun up our current server, keith, on 1 June 2010. His current uptime is 329 days - not bad! He's a pseudo-cloud server with LiquidWeb, meaning his hardware has changed a little as we upsized and downsized him over the years. Currently he's a Xeon X3440 with RAID 1 and 8gb of RAM.
keith replaced mortin, our last physical server at a colo, and one of the very first 64-bit web servers ever put into service anywhere. AMD gave us a pair of their first Opterons to show them off! mortin replaced bart, the server that we cobbled together in a mad scramble back in 2003.
For those not aware, the site's founder was Keith "Mortin" Whitsitt (the namesake of these last two servers). He died in 2004. Bart Williams, the namesake of the first, was an avid, founding member of our Folding@Home team who passed away in 2002.
We're moving on to a new server very similar to keith (except with a Core i5-760) primarily to start with a fresh disk image. There were some issues with how poor keith was configured that have haunted it ever since. This will allow us to finally improve search around here, and give me fresh confidence about ordering up future improvements.
I'm aiming to do the migration this weekend, probably Sunday, if all goes well. It's about 50/50 right now whether that'll happen. I'm still doing basic setup, to be followed by testing of the new installations. There should be no downtime, only some read-only time (no commenting) during the final transfer. (Obviously it won't remember discussion 'read' status either during that time).
One more thing.
The new server's name is spencer.
I expect it will be optimal.
