[ILUG] OT: Routing problem in inex

[Barry Redmond]

The problem has nothing to do with heanet.  The problem exists if I 
use a DIT host or an IOL dial-in connection.  I guess it's the return 
route that gets screwed up.  According to the acm tech support 
person this problem only affects Dublin (and I presume the rest of 
the country).  The identification of the box in inex was done by 
them - I have no details of why they point the finger there, but I 
have asked and I hope to get info later today when they get out of 
bed.

If anyone wants to see this problem for themselves, try a traceroute 
to www.acm.org.  Actually, I'd be very interested to hear from 
anyone who manages to connect.  Might help to narrow down the 
problem.
