Missing / broken routes?

Reported by: Ray.Bellis@… Owned by: jim@…

FYI - I'm seeing broken connectivity to some destinations:

% traceroute
traceroute to (, 64 hops max, 52 byte packets
1 (  1.187 ms  9.182 ms  1.906 ms
2 (  2.324 ms  1.069 ms  2.025 ms
3  * *^C

% telnet 80

% traceroute
traceroute to (, 64 hops max, 52 byte packets
1 (  1.259 ms  0.632 ms  1.247 ms
2  * *^C

If I VPN via my Amazon EC2 instance I can reach both of these.

kind regards,

Ray Bellis

I've lost connectivity into RIPE's web sites, too.

% traceroute

1 ( 1.736 ms 0.912 ms 0.548 ms
2 ( 1.356 ms 0.804 ms 1.225 ms

This happened about 20 minutes ago for 5 minutes, was then OK, but is broken again right now.

Everything seems to be working now ... we're guessing that one of our upstreams was doing maintenance this morning. We'll check with them, and keep this ticket open for now. Please let us know if you have any continuing problems.

From where I am here on the ietf-a.1x network I'm still seeing the exact same results.

comment:7 Changed 10 years ago by Ray Bellis

that is, RIPE is OK now, but the originally reported routes are still down. I also can't reach (some?) other Akamai hosted sites, e.g. Nor can I reach the other sites reported by Steve Conte.

I'm on the ietf-a.1x net as well and am reaching all of the sites you mentioned. Including from steve.

When you have a minute, could you swing by the NOC (in Chez Luis) to figure out the differences in our behaviour?

Sure, will come around in about 20 minutes or so.
