This work has been completed and traffic has been rerouted back to our London availability zone restoring full redundancy.
We have taken this opportunity to update the TLS certificates on the London Edge to improve compatibility as noted in a previous maintenance window.

Scheduled maintenance is currently in progress. We will provide updates as necessary.

We will be performing maintenance on one of our container hosts in Volta as part of planned maintenance on Saturday morning. We do not anticipate any impact to services but will be shifting traffic away from London for the duration out of caution.
Site specific IP addresses will failover between nodes but may see brief windows of inaccessibility. DNS will be updated to direct traffic to other sites for customers configured in accordance with our interop. Our interop specifies that customers should not send directly to an IP address and, if doing so is unavoidable or for those with wrongly cached DNS, customers should configure their own fail-over to other sites. Anycast services will be served from the next closest node but routing will change.
This maintenance should therefore not be service affecting but the network is considered at risk through a reduced level of redundancy during it.
