At 6AM on Monday, March 21, we will be migrating the following networks to our new border firewall:
220.127.116.11/27 (Instructional Support Group servers)
18.104.22.168/26 (IRIS NetApp file servers, including home and project shares)
There will be a brief interruption to these networks as they are migrated. This will affect all home, project, and other file storage provided by the IRIS NetApps. After the migration, we encourage system administrators to test that connections to the NetApps are behaving as expected. Some file service clients may need to be rebooted or have their nfs service restarted.

As a performance measure, we will be introducing some new IP addresses for some of the hostnames, very early on Tuesday, March 15. If you have any custom firewall rules for the current IP addresses, you may need to modify them to include the new ones.
This change should not create any interruption in service. Any active mounts of the former IP addresses will continue to work.[Read more…] about Change of Some Fileservice IP Addresses March 15
