mikrotik.com ipv6 problem?

RouterOS General
1

I can only get to forum.mikrotik.com/www.mikrotik.com with ipv4.. ipv6 (At least via he.net) isnt working…

Only me?

Mikrotik IPv6 addresses
2 
telnet -6 forum.mikrotik.com
GET / HTTP/1.0

works fine for me. AAAA record resolves.
That’s behind a HE tunnel as well.

I have similar problem with routerboard.com

tracing from several of HE routers, the web site is unavailable over ipv6…

while at the same time over my other ipv6 BGP session from Cogent:

I think that ipv6 internet is very broken at the moment… :frowning:

If you get your IPv6 via BGP from someone then be aware that under ROS 4 it’s buggy and unstable, try restarting the BGP peer and see if that helps

no… my BGPv6 sessions are on Cisco ASR 1006, via tunnel to Hurricane Electric, and native to Cogent…
so no problem there… and I don’t have problems accessing the rest of IPv6 internet, just the route 2a02:610::/32, AS2588 Latnet ISP.
can someone confirm/replicate the issue?

yesterday was the problem only with routerboard.com, but today also with mikrotik.com and its subdomains.
