Re: Very strange connection issue with subversion

Hi All,

Miracle happens, the strange problem mentioned below seems resolved it
self now, after hours of troubleshoot and hair pulling.

I guess it was some network packet filtering issue on one of the ISP's
routers.

Just for the record, the problem lasted over 25 hours, and we spent at
least 3 hours trying to find the cause.

Have a good weekend everyone!

kind regards,

Frank Liu
