The issue appears to be the result of connectivity and authentication issue with our database, further investigation will be required later today to see if we can find a root cause beyond this. The site is now back online and we continue to monitor for any further issues. Due to the extended downtime and issues we are aware that some content may not be processed now due to the limits on our content processing and there may be delays or missing federated content in addition to this due to the 7 hour outage.
