Certificate chain expiration

Resolved Posted by Cody Hammock on June 02, 2020
Outage start Monday, June 01, 2020 12 a.m.
Expected end Tuesday, June 02, 2020 4 p.m.

Due to a certificate expiration in the trust chain for the certificates providing SSL for Chameleon, some clients (e.g. Swift) could no longer verify the SSL termination for the endpoint. To correct this, a new chain was generated using https://whatsmychaincert.com and verified at that same site.

The outage is resolved.

We experienced an outage starting at Februar 22, 10AM CT at CHI@UC due to its database going down. We have since recovered the database and restored all site functionality. No data loss occurred. This should not have affected connectivity to running experiments. However, CHI@UC and the Jupyter environment were effectively down.
