I'd wait a bit for the postmortem; I don't think there's reason to conclude at this time that your traffic is going through someone's centralised load balancer. Another update says that the load balancer issue triggered a bug in Firefox, so presumably fixing the load balancer issue will prevent that bug from being triggered, and then the bug can be fixed separately after: https://bugzilla.mozilla.org/show_bug.cgi?id=1749908#c21

But mostly: I have no real idea what's going on, so I'm awaiting the postmortem.
