News - Jan 2004

Jan 28 2004 - An important ACCC ISP (Level 3) peering session was interrupted briefly late this afternoon for roughly 3-5 minutes and yesterday for an even briefer period. We have opened a trouble ticket with Level 3 asking them to investigate the brief peering session drops. Should a planned service impact arise, we will post an update to this list. Please note that UIC's network traffic to Urbana was not disrupted today nor yesterday as a result of network trouble at Level 3. Thank you. ACCC NOC

Jan 21 2004 - Same problem as yesterday - not enough RAM and swap. We are working as fast as we can to ready a new larger server. Thank you for your patience - we regret associated inconveniences.

Jan 20 2004 - The server was down from 1:15pm until about 2:00pm. We are aware of the cause of the problem and are taking steps to prevent future occurences. We regret any inc onveniences caused.

Jan 17 2004 -

Tigger will be down (including for email) starting Saturday January 17 at 8:00AM until Sunday January 18 at 4:00PM to upgrade its operating system level to AIX 5.2. We may finish what should be a 6-hour job more quickly than that, but with this type of work, anything that can go wrong usually does, so we are reserving some extra time.

This weekend was selected due to the university holiday on Monday. An earlier attempt to make this upgrade during Winter Break ran into trouble, or else we would have done this before classes started.

Jan 17 2004 - We postponed the upgrade to give us time to test contingency plans. The upgrade will be re-scheduled in a week or so. Tigger will be available, as usual, over Jan 17-19.

Jan 15 2004 - Today, Thursday, January 15 ADSM and the dsmc command on the ACCC UNIX workstations will be 5:00PM due to upgrades in progress on its server. All backed up files will be available for restore after that time.
