Maintenance Completed Short Notice Maintenance - 14.08.2018 22:00 BST

Matt

Owner
Firstly, please accept my apologies about the short notice on this maintenance.

Tonight, at 22:00 BST (21:00 UTC),there will be service impacting maintenance on 2 of the shared hosting servers, cp1.mattwservices.uk and cp2.mattwservices.uk

The maintenance is to add an additional 32GB of RAM to each of the servers, to give additional resources and allow for further growth.

Please be advised the downtime could last up to 30 minutes, however, it is more than likely expected to take 15 minutes. All services will be shut down prior to this, to ensure no corruption or loss of data prior to the servers being powered down for the work.

I will send a follow up mail tonight once the work has been completed.

RAM upgrade completed. Servers are back online. I'm going to use this opportunity to perform a full OS update and reboot again into the new kernel that is available.

cp1.mattwservices.uk is now completed.

There is an issue with cp2 where one of the NVME drives has been taken out of the raid array on the second reboot, so I'm having the DC replace the drive.

There will be another short period of time when sites are down while the server is powered off to replace the drive.

Drive has been replaced, and the raid array is now rebuilding
