Slow event processing in AWS US

We're investigating possible intermittent slower event processing in AWS US stack (https://connection.keboola.com/). The API response can be delayed up to 2 seconds. This may cause 

  • poor UI response and
  • slowing down of jobs that write metadata (e. g. column datatypes).

This issue does not cause any job failures.

We're sorry for this inconvenience. Next update in 24 hours or as new information is available.

UPDATE Dec 4th, 15:00 UTC We have identified a few possible root causes of this issue and minimized the impact. The situation is now stable, but we're monitoring it closely. 

This is the last update and we'll reopen the communication here only if the situation escalates.
