[Completed] Upgrades and minor service interruption

In order to improve the performance of our email services we are performing an upgrade to our storage servers.

On Sunday, July 07 at 08:30 CEST (06:30 UTC, 02:30 EDT) we will perform a server hardware upgrade that may cause email service downtime for 30-60 minutes. The upgrade involves installing more memory (RAM) and NVMe based ZIL/write-cache disks that will increase performance.

Incoming email will be queued on other Runbox servers and will be delivered once normal operations have been restored.

The upgrade will be completed as quickly and safely as possible to limit the extent of the downtime.

We apologize for the short notice, and for any inconvenience the downtime may cause.

update 08:30 CEST (06:30 UTC, 02:30 EDT) 

We have now started the upgrade process by shutting down one of the storage servers in order to install the hardware upgrades.

update 08:40 CEST (06:40 UTC, 02:40 EDT) 

The hardware installation is complete and the server is being restarted.

update 08:45 CEST (06:45 UTC, 02:45 EDT) 

The storage server has been restarted and services are coming back online.

update 09:15 CEST (07:15 UTC, 03:15 EDT) 

The write-cache disks have been activated and the upgrade procedure is completed with the expected improvements to performance.

All services are now operating normally and queued email will be delivered.

update 11:30 CEST (09:30 UTC, 05:30 EDT)

There have been minor issues with email message access for some users that should now be resolved.
