1. Scheduled maintenance
Material planned maintenance should normally be announced through the status page, customer portal or email with reasonable notice where practicable.
2. Emergency maintenance
Emergency work may occur without advance notice when necessary to address security risk, hardware failure, network instability or urgent supplier incidents.
3. Maintenance windows
Products may have preferred windows or region-specific schedules. Enterprise customers may negotiate custom change windows where feasible.
4. SLA
Treatment of maintenance in availability calculations is governed by the applicable SLA.
