“ip route” causes problem

After I re setup the server, there are two weird things happened.

1) I use SSH remotely access the server, after I input the password, it took me about 20 seconds to login in.
2) some clients complained that they could not access the website whereas others could.

After dinner, I came across my friend’s home, in his computer, the website could not be accessible.

Then, I was thinking … he used different ISP, the ip address in his computer starts with 64 whereas mine starts with 24.

I login the server again and type "ip route" and found there was an entry forward all ip start with 64 to one special ip address.(who set this?)

After I deleted this ip route, the two problems above are gone!
