Issues with tserv1.lon2

Well, after having no end of problems with IPv6 connectivity to external sites, I've had to completely disable all IPv6 access on my network. Anyone else having problems?

I can't get to the Azure portal for example, nor does the Microsoft store work.

As soon as I remove IPv6, everything works with no problems.

Same issue in the UK, looks like an MTU issue somewhere on HE's side. I've enabled TCP-MSS clamping down to 1370 and that is working around it for the time being, can't seem to go much higher than that.
