Can someone ask Canonical to reboot their server that serves out metadata about which file is in which package? Or is this their response to the Red Hat / Centos kerfuffle? Or were we supposed to use the debian site? It's entirely possible I missed the memo about Canonical EoL'ing support for parts of Ubuntu, but resources that used to work are throwing 500s at the moment.
It seems fine from here. Maybe a result of AWS being down/broken?
