Why SSL-everywhere is not necessarily a good idea in all circumstances

I'm in a remote location where the only comms are via a satellite link. This is what my internet connection looks like at the moment:

    [ron@mighty:~] ping google.com
    PING google.com (4.35.21.152): 56 data bytes

    64 bytes from 67.201.56.75: icmp_seq=7 ttl=46 time=3468.035 ms

Under these circumstances I can just barely open a regular HTTP connection, but most HTTPS connections time out before they can be established. So I can't do a Google search :-(

(Even submitting this to HN required multiple attempts.)
