After 21:15 on Thursday 12th February a new firewall will be activated, and a subset of traffic will be rerouted to the new firewall. This work will require an outage to webservices of between 30 to 90 minutes while reconfiguration takes place.
Where it is appropriate we will be contacting individual stakeholders to invite them to perform additional service verification when the work is completed at approximately 22:30 on the night of 12th February.
