The following incident was caused by our transfer process losing connection with it’s database at the end of it’s transfer. How it loses it’s connection seems to be caused by a timeout setting. The setting doesn’t seem to be configured in the database itself, but in the networking layer supporting it, so it was harder for us to discover the issue. The database we use is a managed redis that is provided to us by IBM cCloud Databases for Redis. The issue started occurring after our maintenance window because we changed the code that was responsible for connecting to redis. We will be reviewing our QA processes to ensure that a test case is created for this specific scenario.
