Help Desk Thanksgiving Holiday Hours

The UMIACS Help Desk in AVW3142 will be closing our doors early, (3:30pm on Wednesday) to prepare for the upcoming holiday weekend. After this time the best way to get help will be to send mail to staff@umiacs.umd.edu. Additionally the Help Desk will be closed and there will be no staff on site Thursday and Friday, as a part of the University being closed for the Thanksgiving Holiday. We will re-open as usual Monday, November 29th at 9AM.

AV Williams Building x300 and x400 wings, November 20th 10pm - Nov 21st 6pm

Facilities Management plans to complete replacement of the AV Williams North UPS on Sunday Nov 21. This work will require a power outage of the North side of the AV Williams Building, which includes offices in the x300 and x400 wings and the secondary data centers in 4464 and 1446. Staff will shut the Chimera Cluster, Crocco Cluster, RDEC Cluster, and Lattice Grid down before the outage starting at 10pm on 11/20 and will be on-site to bring them back online afterwards. We will make every effort to bring them back online by the start of the business day on Monday November 22nd.

The main UMIACS data center will not lose power and all of the Institute's core services will be available during the work.

Please send mail to staff@umiacs.umd.edu with any questions or concerns.

Comcast DNS Issues

We are currently experiencing issues with Comcast home internet in PG county not correctly handling DNS resolution for UMIACS hostnames, that can seem to be affecting connectivity to UMIACS.

If you are having problems getting to UMIACS hosts you can use our name servers to resolve those specific host names then connect using the IP addresses you lookup. Our name servers are 128.8.120.19, 128.8.120.50, and 128.8.132.75 to use this information to get the ip address of the host somehost.umiacs.umd.edu you would use the command "nslookup somehost.umiacs.umd.edu 128.8.120.19", from a linux, windows or mac command prompt.

Unfortunately the problem seems to lie in an interaction of Comcast's name servers with those run by OIT, but we are looking into ways we can interact with those parties to get this issue resolved. <endFeed />
