RE: MSN blocking transport IP?

Hi

I have a jabber server with PyMSNt running with about 4000 active msn
users at a time in several instances of the transport, last week i have
been experiencing a lot of disconnections form msn servers until this
moring, when i could not stablich more than two or three connections at
a time, so i migrated the transports to another network from wich the
connections began to work without problems, currently more than 1000.

Is it posible MSN is blocking my IP?, is anyone experiacing the same
problem?, if so, does anybody have a solution for this?

Thanks
