On June 14th at 07:48 UTC, we started to receive isolated reports of MURAL users in Europe being unable to access their murals. At 08:48 UTC we confirmed this was an issue affecting a significant proportion of MURAL users and escalated this to our incident response team to commence investigations.
At 10:25 UTC our cloud provider confirmed there was an issue with their portal (see https://status.azure.com/en-gb/status/history/ for more details). This was confirmed to be the root cause of the issue affecting MURAL users.
At 12:16 UTC, in collaboration with our cloud provider, we successfully updated our connection to the Azure portal. By 12:50 UTC full connectivity and service in MURAL had been restored.
This incident resulted in 5 hours 2 mins of downtime. No data from prior to the outage was lost during this time.
