It looks like a DNS issue and that's what I thought it was (hangs on "looking up hostname"), but unblocking the phorm addresses solves it.
Anyone else seeing this?
I should add that if I unblock the addresses and visit a site which was unreachable with the addresses blocked, then after visiting I can visit again no problem with the addresses blocked.
I have the following blocked:
88.208.248.102 - 88.208.250.85
phorm.com
Hmm, I can't even get to my modem configuration page (192.168.100.1) with those blocks.
Not just http, but ftp as well.

I'm still seeing this behaviour today.
I've narrowed it down to the blocking of phorm.com.
Is no one else seeing this?
Does no one else have phorm.com blocked?
Seriously, no internet connectivity unless phorm.com is not blocked -- what else can that mean but all my internet activity is passing through, or relying upon a response from, phorm.com at some point?
