The issue has been resolved, all services are operating as expected.

Thank you for your patience, apologies for any inconvenience caused.

Core services have been updated to not depend on the failing connection, allowing them to start up normally.

This reconfiguration has allowed all services, including the network stack, to come back up.

The root cause of the issue has been found.

Services have failed to automatically recover due to a misconfiguration in the networking stack on our core instance. A fix is being implemented.

The cloud provider has restarted the server instances, however services have failed to automatically recover.

The cause of this is under investigation.

Our cloud provider is deploying a security patch to instances, causing the instances to be unavailable for approximately 30 minutes.
