Maintenance windows
Planned maintenance is scheduled outside CET business hours wherever possible and announced in advance. The product is designed so a customer in a different time zone is not woken up by routine maintenance; emergency security patches are an explicit exception and are announced as soon as the patch is decided.
Where to verify
For service health: this page (live feed link to follow). For changes to the documentation that governs the service: the Updates page. For everything that affects the contract (terms, DPA, AI Annex, sub-processor list), the matching page on this Trust Center is always the authoritative version, and your personalised PDF in the admin panel carries the matching version stamp.
