There are still 198 hosts hitting the legacy metadata download endpoint that was retired on February 14, 2018. The metadata validity window for the last metadata these hosts successfully downloaded from that endpoint is tomorrow, February 27, 2018. Any hosts still dependent on this metadata for the functionality of their SAML deployment will FAIL tomorrow. Please search this set of lists for your organization and its hosts and remediate them now.
