Abusive traffic from Microsoft China?

Thu Nov 8 17:22:43 UTC 2007

Just wondering if anyone else is seeing huge random
floods of traffic from:

inetnum:      202.96.51.128 - 202.96.51.255
netname:      MICROSOFT-CO
descr:        Microsft (China) Co.Ltd
country:      CN
admin-c:      CH455-AP
tech-c:       SY21-AP
mnt-by:       MAINT-CNCGROUP-BJ
changed:      suny at publicf.bta.net.cn 20060926
status:       ALLOCATED NON-PORTABLE
source:       APNIC
changed:      suny at publicf.bta.net.cn 20060926

On a nearly daily basis we see them randomly open
thousands of connections from a variety of addresses
in that block to multiple servers.  I've emailed
of coruse but that results in nothing.  Probably
will just end up blocking them.

Thanks,

David
