August 2009 Archives

Snow Leopard should be available from Titles later this week. By early next week I should have had a chance to investigate incompatibilities and try an upgrade myself.

The compute servers were brought back up at 9 AM. The primary file/web/mail servers (and thus the workstations) remained up all weekend as the server-room stayed relatively cool even without the AC running.

As announced earlier, the compute servers will be down from Saturday evening to Monday morning while the AC is turned off. The main servers (web, email, workstations) will stay up unless the server room starts to overheat.

The unexpected downtime which started at 7:20 pm was resolved at 8:15 pm.

The file server didn't come up properly after a routine reboot. I'm working on the problem. Most web sites are up; email and workstations are down.

The main server (mathserv) will be rebooted at 6:45 pm this evening as the final part of today's maintenance. Mail, web and workstation access be interrupted for ca. ten minutes.

Workstation and mail were back on line as of 5:20 pm following the performance updates. Workstations may be sluggish for another hour as some system work continues in the background. You should reboot your workstation if you see anything strange, though it may not be necessary.

The downtime announced for 3 pm to 7 pm today began at 4 pm and should finish by 6 pm. Workstation access and email are down; web sites are (mostly) up.

Mathserv and dependent workstations and servers are a little slow right now due to some work I'm doing on the main file system. Things should be limber again by 9:45 pm.

The compute servers will be down Saturday evening & all day Sunday (Aug. 29, 30) because the campus air-conditioning system will be turned off. I hope to be able to leave the email/web/workstation servers up, but they will be shut down if the room becomes too hot.
See the original announcement for details.

The HH/BSB workstations and email access will be down Thursday afternoon between 3 pm and 7 pm while I perform some maintenance and updates to improve performance and capacity. Web sites will be up most of the time.
