Update [17/05/2024 09:01]

What initially looked like a line card failure turned out to be a software issue that caused a core switch to reboot. Most likely bug related. Raised with vendor TAC for further investigation. The outage was under 30 minutes for some circuits terminating at Telehouse West.

Investigating [16/05/2024 23:55]

We are investigating a failure at Telehouse West owing to a line card failure.

A small number of broadband sessions may have been impacted, but have since recovered.

All leased line circuits have now recovered, and engineers are looking into the cause.

Scheduled [16/05/2024 11:56]

We will be performing essential maintenance on Shared Windows Server 19, which hosts a web site / domain name under your account.

This will take place on Tuesday 21st May 2024 at 730PM (1930 BST)

During this window, we will be upgrading the MySQL Database server on the machine from 5.7 to 8.3. MySQL 8.3 offers improved security, performance, and manageability over 5.7.

Please note the following

- The upgrade is only happening on Server 19 on that date - we will be updating other servers on Linux in due time.

- We have performed many checks and trials on mirrored development servers, and customers should not experience any issues after the upgrade completes.

- We will be performing a checkpoint on the web server, meaning we will be able to roll back if needs be.

- Once the upgrade has completed and works as expected, it will not be possible to roll back to a previous database version.

- During this time, sites relying on MySQL database connectivity will not be available.

- Sites running Access or Microsoft SQL Databases will not be affected by this, unless a roll back is required.

- We believe the process should take no longer than one hour to complete.

If you have any queries regarding this upgrade, please do not hesitate to reply to this email.
