   Between 12:10 and 12:23 PT (19:10–19:23 UTC), a degradation caused most API requests to get, list, update, or delete browsers to fail with 500 errors. Some browser create requests also failed, and browsers that were already running may have had network or proxy connection problems during this window. We rolled back the deploy and error rates returned to normal at 12:23 PT. We're monitoring to confirm everything stays stable. If a browser created during this window is misbehaving, delete it and create a new one.
