try a sniffer (tcpdump, wireshark, ...) - if you have timeout with every remote server, then you have a borked box (known bugs: tcp windows scaling, delayed ack, ... etc.) or a borked firewall setup (common silly setup: block all icmp). - if you have timeout with few remote detinations, then they might be blocking you, rate-limiting you, foobaring you. you can try sending them mail from gmail (for example) and see.
