RCA
After a network recovery event, the connectivity with the storage nodes was not successfully restored on certain nodes causing unresponsive infrastructure nodes.
To resolve the issue a restart of the affected nodes was required.
As advised by our upstream supplier, infrastructure changes were implemented to maintain uninterrupted availability of the storage when reconnecting after a network recovery event.

Redwood Engineers working with Amazon have identified a potential performance issue between the Redwood infrastructure and Amazon storage services. We have deployed a fix to our infrastructure for which a restart of the environments is needed. The restart will automatically migrate the environment to the infrastructure that has the fix applied.
Please verify which of your environments will require a restart. The environment names are displayed in the MOTD you received or by checking the RMJ/RMF Dashboard

If the option to reschedule a restart is not displayed in the Dashboard, no restart of that environment is needed.

Dear Customers,
We have created this knowledge base article to keep you apprised of the current developments regarding the outage that started on the 9th of August at 00:00 UTC in the Dublin Region.
Our monitoring system immediately identified the ongoing issue, and our Engineering team was notified.
We are actively working on the recovery of the environment(s) that is(are) affected.
The current focus of the team is to bring affected environments to a running state, once that is completed and the environments were verified, the team will work on providing a more detailed RCA.
We will keep posting regular updates in this KBA.
