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.
