Seems to be some weird underlying issue going on at GCP at the moment. Had cloud build webhooks returning a 500 error. Noticed we were at 255 images and deleting some fixed the issue. Created a P2 ticket about the issue before we managed to solve it and haven't had a response in 40+ hours. The timeline of this disruption matches when we started experiencing cloud build errors.
