It most likely is. We are using Ubicloud (which seems to work the same way hf jobs does) and it's also down. GitHub is not sending out Webhooks and is also not able to queue external jobs. If we had to emergency deploy anything now I'd have no idea how to really do that...
I am not sure if all Webhooks were affected or only those regarding actions. Theres not much information given besides "Webhook deliveries may be delayed."
