Maintenance

Release upgrades and other system maintenance are done in quarterly maintenance windows on RTC day. There are one or several short service breaks during the maintenance window. Maintenance windows for each region are:

• Europe: Sat 4 PM – Sun 10 PM UTC
• Americas: Sun 1 AM – Mon 7 AM UTC
• APAC: Sat 10 AM PM – Sun 4 PM UTC
• Africa: Sat 4 PM – Sun 10 PM UTC

Maintenance windows are excluded from availability calculations. In case there is a need for maintenance outside quarterly maintenance windows, customers are notified separately.
