This is a swing from one mainframe environment to another in order to be able to perform maintenance tasks. It is important to note – the swing happens every weekend, hence this will be recurring planned service degradation. Of course, this is not the way we want to keep it, however since it is related to very core, mainframe systems, the fixes will not come that easily. At the moment, we target to mitigate the causes for the errors in Q1 2020. Apologies in advance for any inconveniences caused.
