My guesses:

1) Reverse DNS problem. The DNS server for the reverse resolution of your IP is playing up. That's why you can connect, but nothing appears to happen (or it takes a long time)

2) TCP MTU or MSS problem. Something in between you and your server is quietly dropping packets that are becoming fragmented. Perhaps a router is also blocking the ICMP message that goes back to you to say "you're sending packets that are too large" (this was a common problem when PPPoE first appeared and shaved several bytes off the default maximum packet size... many sites indiscriminately block ICMP to block pings so it kills off legit msgs too)
