I'm not sure if this is a particularly good venue for this. But you mention neither source IP nor the target IP Google returned to you using DNS.Hi,

at the moment(for 8 hours or longer) seems to be a problem between
google and Deutsche Telekom (AS3320).

I am wondering about just one person (forum at telekom) and I
complaining it.

Can anybody confirm or solving the problem?

A lot of google-services load very slowly(fallback to IPv4), also
websites with fonts loaded from google.

googles public-dns is working, but no other things.

Thomas

Hi,

I can confirm I am also having issues reaching anything behind 15169 via
3320.
Example src: 2003:de:4be0:a800::/56, dst: 2a00:1450:4016:804::2003.
$ traceroute6 google.de
traceroute6 to google.de (2a00:1450:4016:804::2003) from
2003:de:4be0:a800:cd43:321a:ad4e:b726, 64 hops max, 12 byte packets

Please send a traceroute or mtr (offlist is fine).

I don't have any insight, but it could be that Google is now doing the
same thing to DTAG as it has done to Cogent for a few weeks, ie
specifically ask its transit partners to not announce 15169 routes to
AS3320, and deciding AS15169 now to be IPv6 Tier1, and if you don't peer
with AS15169, you're not getting the routes.

It is curious the local preference is not 100

It works again.

There was a "nice" map:
