Ticket Opened: Problem Start: 19990630 09:00 UTC+1
Ticket Closed: Problem End:
Throughput between HEAnet and BBNPlanet is currently below normal
Access to parts of the internet beyond the US. Other parts are
unaffected, as are INEX, Janet and TEN-155 traffic.
Cause of problem is being determined
Update 19990630 11:00 davew
Seems to be an upstream routing problem specific to HEAnet addresses.
Some sites work fine; others are accessible by Esat addresses but not
HEAnet. Esat are working on the problem from their end and we're
continuing to investigate.
Update 19990630 13:15 davew
Problem seems to be specific to sites taking a particular route
out of Esat Net. Access to these sites are flapping independently
of each other, slowing the investigation.
Update 19990630 16:15 davew
Seems to be due to problems on the BBN line itself; Esat's BGP
session is going up and down. Some parts of the internet are
damping our routes. Line is due for testing at 19:30 (see ticket
HEA-NOC/19990630-02), Esat are arranging for alternate route
Time to Fix:
Still working on it.
