Problems with AS40015 and AS30071 <--> AS3320

[Thomas Schäfer]

Hi,

I am in conflict with the support of Deutsche Telekom (AS3320). They
check my DSL-connection again and again. And I try to explain that there
must be a bigger problem.

The problem itself is very simple:

bin6.it

v6.testmyipv6.com

are not reachable from the network of Deutsche Telekom ( DSL, LTE, - no
route to host)

>From some other hosts e.g. my workplace at DFN/LRZ it works, at least
ping, at the moment port 80 seems to be down.

Also http://ipv6-test.com/validate.php indicates that at least
v6.testmyipv6.com is alive.

Is somebody here, who could confirm or better fix the problems between
these AS?

Regards,
Thomas
