We're having a temporary issue with the database cluster, earlier today a few nodes crashed beyond recovery, one thing lead to another and eventually the entire cluster crashed. Up until the full crash occurred you could experience slow loading times seemingly randomly and after the crash you may have seen this error message:
"message": "database cluster appears to be temporary unreachable, please try again later.",
All data is safe. We don't put our faith in one single point of failure. However, the latest snapshot is being restored to a new cluster at this moment. Expect a few more minutes of downtime but after that everything should go back to normal again.
