I got this block notification earlier today Given that usertrust.com is owned by Comodo I'm not sure what's going on here. So I'm guessing it's the IP 22.214.171.124 that's the issue. The IP doesn't appear to be owned my Comodo. And in fact if I run an nslookup on the A record for ocsp.usertrust.com I get 126.96.36.199 back. So I'm curious as to what might be going on here. Is it a false positive or a deeper issue?
