BWRC Network Downtime

February 8, 2006 by Janet Shu

BWRC network will be down on Monday, February 13th and Tuesday, February 14th.

BWRC has been running on the original Bay Networks data switch hardware since the Center opened. We will transfer all data traffic to the new Extreme Networks “Alpine” switch. One to two days disruption will be involved for a significant fraction of the BWRC client machines.

During the initial part of the transfer process (2-4 hours), there will be no network connectivity at BWRC. After the initial period, all core servers and services should be back on line.

During the remainder of the process we will be hooking up the data connections for the regular BWRC clients. This is likely to last into a second day. Please use the EECS wireless network while you are waiting for your deskside machine to be hooked up.

If you have an urgent need for the earliest possible access, please reply indicating which port or cubicle you need access for and what the nature of the urgency is. We’ll review and give these requests priority as is possible.

Please make your plan accordingly.

Loss of connectivity to border router through EECS firewall

February 1, 2006 by IRIS Staff

Beginning last evening and continuing off and on this morning, we have experienced some loss of connectivity to our border router through the EECS firewall. We are seeing very high CPU utilization on the firewall and, as a result, some packet loss to and from the border. I have opened a case with the vendor and we are actively pursuing the issue.

Please bear with us.

Soda Helpdesk on a Reduced Schedule Indefinitely

January 30, 2006 by IRIS Staff

Due to continued staffing and scheduling constraints, the EECS Helpdesk in 313 Soda Hall will be operating on a reduced schedule and will be open 9:00a–1:00p, M–F from now on, unless otherwise noted.

This does not affect the Helpdesk in 395 Cory Hall, which will continue to be open during normal business hours.

We apologize for any confusion this may cause our customers in Soda Hall. We think that a reduced Helpdesk presence is better than none at all and will be working to increase our personel in order to be able to adequately staff both locations.

Main UPS down

January 27, 2006 by IRIS Staff

The main UPS in Soda 290 computer room failed this morning. It is now on bypass mode, which means our critical servers are now on city powers only. The staff is working on identifying the cause and working on a solution, including get vendors to do onsite emergency repairs. However, there is no estimate when this will be fixed.

Since our servers are now without the protection of UPS, we want to let you know that we are subject to power outages. If that does happen, there could be considerable downtimes. We will update the status over the IRIS website and helpdesk phone.

Thank you for your understanding and cooperation.

There will be a network downtime on Thurday morning Jan. 26 between 8:00AM and 9:00AM. We will be upgrading network firmware for the BWRC switch.

This will affect users who use a wired connection in BWRC. Since the BWRC wireless network feeds into this switched infrastructure, there will also be an outage to the wireless network in BWRC.

I regret any inconvenience this may cause. Please make your plans accordingly.
