Everything seems back to normal. We've identified the issue and will deploy a preventative fix before revisiting adding load balancers.

We've removed the new load balancer from DNS. It will just take a little time to allow that DNS change to propagate, after which the errors should subside. We're continuing work on preventing the issue, before the new load balancer can be re-added.

Some customers are reporting that they are being signed out of Tracker and that their private projects are displaying that they are public. This is just a display issue - all private projects are still completely private. We have discovered that an issue that was rare and unreproducible is now being exacerbated by a new load-balancer. This has allowed us to work on the fix.
