All appliances are back online following their respective reboots and are routing traffic as expected.

We did not observe any major disruption to services hosted in Data Centre 1 (DC1).

Maintenance is now concluded.

Primary appliances have completed their respective reboots. We have confirmed they are routing traffic as expected, and we have initiated the failback of production traffic.

Secondary appliances are now undergoing the firmware upgrade.

Primary appliances have installed their firmware upgrades successfully and are now reloading to apply the new firmware.

We have confirmed that traffic has failed over to secondary appliances successfully.

Maintenance has begun.

We have initiated the upgrade process on the primary routing appliances.

We will be upgrading the firmware of our routing infrastructure on 08-Sep-23 at 20:00.

We anticipate the upgrade to proceed as follows:

• -19:00 - First set of appliances upgrade, connection flows are cut and migrated to warm-standby infrastructure while the upgrade is completed. <1-second disruption while connection flows are re-established.

• -19:15 - Verify upgrades completed successfully and primary appliances are fully functional. Initiate upgrade of the second set of appliances.

• -19:30 - Second set of appliances upgrade, connection flows are cut and migrated back to primary routing infrastructure while the upgrade is completed. <1-second disruption while connection flows are re-established.

Our routing infrastructure is fully redundant, as such we do not expect any major disruption.

We will update this page once the upgrades have been completed.
