Re: Level3 routing issues?

This is definately a world-wide problem.

Many networks are reporting all sorts of things. Nothing clear, except
that it's all aimed at 1434.

01:28:33.331686 64.21.34.210.28295 > 238.192.142.61.1434:  udp 376 [ttl 1]
01:28:33.331720 207.99.21.121.1917 > 226.39.19.228.1434:  udp 376 [ttl 1]
01:28:33.331772 64.247.0.168.1379 > 239.194.46.210.1434:  udp 376 [ttl 1]
01:28:33.331841 207.99.77.34.3894 > 227.154.8.29.1434:  udp 376 [ttl 1]
01:28:33.331992 207.99.21.120.2558 > 231.16.91.78.1434:  udp 376 [ttl 1]


FYI:

ms-sql-m        1434/tcp   #Microsoft-SQL-Monitor
ms-sql-m        1434/udp   #Microsoft-SQL-Monitor
