google is blocked through my tunnel
« on: September 14, 2012, 04:26:31 AM »

Hi.

Seems like starting from today's morning (GMT+5 here) google is blocked through my tunnel:

[emz@taiga:/<2>etc/squid]# traceroute6 -I google.com
traceroute6 to google.com (2a00:1450:4010:c04::64) from 2001:470:1f08:14c0::2, 64 hops max, 16 byte packets
 1  drookie-1.tunnel.tserv5.lon1.ipv6.he.net  93.431 ms  93.604 ms  93.478 ms

 3  2001:7f8:4::3b41:1  89.780 ms !P  89.288 ms !P  89.828 ms !P

As far as I understand !P means it's blocked by a filter. Why ?

Although other destinations seem to be fine:

That !P is a response from a Google router.  Looks like something may be amiss in their EU network.

I send an email with information about this outage to someone I know at Google. I hope he isn't on vacation.

I didn't hear back yet. But it looks like they got the problematic IPv6 address removed from DNS and replaced with a functional one.

Thank you a lot. It works for me now.
