Already reflected yesterday on https://status.centos.org/ but announcing on centos-devel list as we receive also questions on irc about this (so sending here for awareness) :
Since yesterday, the IPA cluster used for Fedora authentication has an outage (see fedora-infra ticket https://pagure.io/fedora-infrastructure/issue/11733)
Apart from https://accounts.centos.org portal, you'll see issues in centos infra/services using FAS authentication too.
That includes : - https://cbs.centos.org (no group sync) - pushing to lookaside cache (querying fasjson, down at the moment) - eventually requesting new TLS cert (fasjson down) - logging on a service itself using id.centos.org (ipsilon instance tied to IPA and so having issue with IPA backend)
For more information, feel free to watch fedora-infra ticket
