This is the postmortem on the performance degradation of 18/01/2023.
On this date, two internet providers experienced problems independently from each other. These two service providers are mutually designated as failovers, but due to the simultaneous difficulties of both providers, our data center was only accessible to a limited extent, which manifested in long response times or complete inaccessibility.
In cooperation with both providers, we will do everything possible in the future to ensure that this kind of problem will not occur again. We apologize for any inconvenience caused.
