This afternoon, we experienced a DOS attack that was disruptive to our network. The attack caused a software failure on one of our core routers and we had to manually fail over to the backup management module. Additionally, this attack caused a problem with one of our name servers, Rhea. This attack likely was the cause of some wireless controller crashes today as well. We have blocked the offending attacker at the firewall. Network services are now coming back up.

Today, August 24, 2006, Apple issued a recall for some of the batteries found in its iBook G4 and Powerbook G4 laptops.

The batteries are being recalled because they pose a safety threat to users due to severe overheating.

For details, see the U.S. Consumer Product Safety Commission’s website.

To determine if your battery has been recalled or to exchange a recalled battery with Apple, use their battery exchange program.

All, it seems that late this afternoon, we lost routing updates from the campus routers. We have put in a temporary default route as a work-around and campus/Internet connectivity has been restored. We have opened a ticket with campus to see what the problem is. Again, we regret the inconvenience.

Late this morning we had an unscheduled network outage which appears to be rooted in our firewall. The primary unit stopped passing traffic for an, as yet, unknown reason. However, we were able to manually switch to the back-up firewall and traffic has been restored. We are still investigating the cause of the outage. I regret the inconvenience.

We will reboot the switch(Salp3A) on the 3rd floor of Soda on Wed morning Aug 16, 2006. There will be brief network outages at 7:30AM. It should take less than 5 mins.

This will affect users who use wired connection on the 3rd floor with cable-ids starting with 3A-. Since our wireless network feeds into our switched infrastructure, there will also be a couple of brief outages to the wireless network on the 3rd floor of Soda.

We regret any inconvenience this may cause.

Today at 5:14 AM, the switch that serves about half of the 5th floor Soda network connections rebooted due to some errors. While the switch is currently up, it is still logging errors. It is very likely that we will need to make emergency repairs this morning and swap out some hardware. This switch also feeds the wireless APs for floors 5-7 in Soda Hall.

We regret and inconvenience this may cause.

Last night (Thursday, Jul 13, 2006) at approximately 10pm, there was a UPS failure in the 290 Soda Hall machine room. The UPS unexpectedly went into bypass mode and dropped power to all major services within EECS. Service was restored at approximately 10:30pm. A new circuit board is on backorder from the UPS vendor.




There is a possibility that some e-mail to the IMAP server was bounced.
