This incident has been resolved.

As per the AWS status page (https://status.aws.amazon.com/), the issue is recovering. We will continue to monitor until loads get back to typical levels

We are still keeping this issue open, whilst we monitor the load times, until the underlying AWS eu-west-2 is resolved. We are seeing load times coming down whilst we spin up more database instances

We have been able to spin up even more database resources which has alleviated some of the pressure on the running instances and the load time is coming down

It should be possible to access Signable however it may be a bit slower, due to the ongoing issues at eu-west-2.

AWS have confirmed to us that there is an internal issue going on affecting connectivity within the eu-west-2 (London) region.

"[04:24 AM PST] We are experiencing instance connectivity issues in a single Availability Zone (euw2-az3) in the EU-WEST-2 Region."

We have identified wider issues with the AWS London region, specifically one Availability Zone. We are spinning up more database capacity in the unaffected AZ to deal with the increased load causing the slowness

We are currently investigating this issue.
