Hi!

I've discovered, several months ago already, that all the 1&1 web sites
with IPv6 support enabled are broken, because they filter PMTUD, so any
residential customer with has a reduced MTU because PPP or any other
encapsulation/tunnel, etc., is not reaching them.

Do you have an example of a website they host that I can test against?

Yes, it fails PTB test
