We are seeing some deployments timing out. It looks like the retry mechanism is doing its job just fine and deployments are starting anyway for all affected applications but you may be observing an usual delay.
We are investigating this issue.
13:47 UTC: The issue is fixed. All deployments have been working fine during this period, only delayed by a few seconds. The issue came from a misconfigured deployment component which was sending broken messages to hypervisors. The broken component has been dealt with.
