Scheduled maintenance in EU-WS datacenter on Sunday 21st of April

We will be performing scheduled server maintenance in our EU-WS data center. Due to upcoming migration of the datacenter from Linode to AWS a full cluster restart is required. Maintenance is scheduled for Sunday 21st of April at 23:00 CEST (Sunday 21:00 UTC). We expect service degradation (ticket / filters non visible) which will take around ~30 minutes.
