Looks like we have a full house outage at GitHub with everything down. Much worse than the so-called Twitter / X recent speed-bump that was screeched at and quickly forgotten.
I don't think GitHub has recovered from the monthly incidents that keeps occurring. Quite frankly it is the expectation that something will go down every month at GitHub which shows how unreliable the service is and this has happened for years.
I guess this 4 year old prediction post really aged well after all about self-hosting and not going all in on Github [0]
