UMIACS Web/FTP Filesystem migration
When: Tuesday 9/21 10pm - Wednesday 9/22 2am
We are going to be migrating the main UMIACS web and ftp file system to a new backend storage system which will require both the file systems to be read-only and then offline for a very short period. There will only be a 15 minute window at the tail end of the maintenance window where we will not be serving web and ftp content. No other services within UMIACS will be affected.
Please send any questions or comments to firstname.lastname@example.org.
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 126.96.36.199, 188.8.131.52, and 184.108.40.206 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 220.127.116.11", 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.
