Platform Status : No known issues Mar 5 2024 4:38 PM GMT+1
The service is up and running with no known issues.
Joking aside, I wouldn't be surprised if this was the case, because during their last major outage (something related to DNS iirc) they were having issues pushing fixes because they couldn't login because their DNS was down.
EDIT: seems like the status page was recently updated.
