Thanks to everyone for bearing with us through the downtime that we experienced yesterday. This was caused by an issue that AWS had with their servers, so unfortunately was not in our control. As a result of this we’ve looked at how we use their services, and have spread that usage over all 3 of their London zones, rather than the 2 we had previously. This will help to increase our resilience should this happen again.

AWS have closed this as an issue today, so the service should be back to normal.
