Our technical team were advised by our vendors this morning to update the Firewall to the latest version of software and, as part of that process, to restart it. This appears to have restored network connectivity and early indications are showing that there is a consistent standard of performance compared to yesterday. However, the Firewall software update process is still running and may take some time to finish.
With respect to identifying the root cause of this incident we are continuing with our investigations.
We apologise for the disruption this has caused over the last two days. If you do notice any further degradation of service please contact the Service Desk is the usual way.
