To ensure our uptime and security goals are met, we regularly perform maintenance and upgrades on the exchange platform. Such upgrades are always carried out in the least-disruptive manner possible, and always during the following maintenance windows:
Mondays to Fridays between 08:00 and 17:00 WITA (GMT+8).
Saturday or Sunday between 21:00 and 03:00 WITA (GMT+8).
Scheduled maintenance is always announced to the relevant mailing list at least 72 hours before it is taking place. However, hardware or software failure may occasionally require unscheduled maintenance in order to repair. In such cases, an Emergency Maintenance window may be scheduled or commence immediately, depending on the severity. Every effort will be made to notify members of such an event as quickly as possible.
