Hi — we’ve seen a few heavy load notifications in the last 10 minutes.
We’re currently investigating the precise chain of events leading to them but we’re pretty sure that it was a cascade of server failures caused by an over-sensitive health check in one of our load balancers. This is a new load balancer put in place to handle the increased traffic we’re seeing, so we’re still tuning its configuration.
We’ve reduced the sensitivity of the health check and think that that should resolve the issue as we investigate more in-depth.
My apologies if you’re one of the people who saw the heavy load message and my thanks for your patience as we fine-tune the system to handle the greater demand we’re seeing across the site.
