Thank you. A job might not have outbound bandwidth spike. Unless it is the backup job, I do not see the backup for today uploaded to S3. Could it be that? I doubt it retries every 30 minutes. There is nothing abnormal on /sidekiq, will look more closely in some time.

It was the backup. I cancelled the stuck backup process from admin panel and the spikes went away. The backup file did not upload on S3 but it kept retrying for some reason. Requires more investigation at my end.

How do I find out what is causing this spike?
