Update: 4PM 05/11/2022: This issue is now resolved, provisioning and connectivity should be restored for all UC nodes.
An issue is affecting the provisioning of new instances on P3 nodes at UC. Existing nodes are unaffected.

Update: 6pm 05/10/22: The outage is now resolved. Both switches are now functional, and P2 nodes from nc01-nc64 are back online. New instances have no issues, existing instances may still have connectivity issues. If you have those issues, please try removing and re-attaching the network port to your instance.

Expected end | Monday, May 02, 2022 1:17 p.m. |
Update 05/03/22: This issue is now resolved. It was caused by a combination of two factors: misconfiguration of the DHCP behavior for out-of-band interfaces, and a failure causing an out of band switch to power off.
All affected nodes should be reservable again. If you have an instance that has become inaccessable, please get in touch with us via the helpdesk.

Update: This has been resolved as of 11:42 AM, and the site is back up. Running nodes should not have been affected, aside from the temporary loss of network connectivity.
CHI@UC is currently down due to a failure of the controller node's load-balancer. We will update here with more information.
Outage start | Tuesday, March 01, 2022 4:04 p.m. |
Expected end | Sunday, May 01, 2022 4:04 p.m. |
Update: Connectivity has been restored. Root cause was a software bug preventing the creation of a PVST instance on the switch, due to a large number of configured vlans. Using a single instance for all VLANs restored functionality.
The 1g switch serving out-of-band access for nodes in rack BG-41 has encountered a (so far) unrecoverable software error, preventing traffic to the out of band interface on nodes P3-CPU-020 to P3-CPU-038.
Outage start | Monday, February 21, 2022 3 p.m. |
Expected end | Tuesday, February 22, 2022 11:17 a.m. |
Update 11:16 CST: This should now be resolved. A forwarding loop in the underlying network topology caused some ports to become shut down. Instance provisioning and floating IPs should now be working again. Please reach out if you're still seeing issues on the UC site.
We're currently observing networking issues at UC. New instances are failing to provision, and existing ones are unreachable. We're still investigating the root cause, but will update here when resolved. Other sites are unaffected.
