... You could test yourself if you can see http://62.236.221.71 (the problem system) http://62.236.221.78 (another guest on the same xen host)
If someone *cannot* see the 1st one, then it would be interesting to know if (s)he can see the 2nd one or not.
It is the case from 147.99.7.1, and not only for port 80 :
$ ping -c 10 62.236.221.71 PING 62.236.221.71 (62.236.221.71) 56(84) bytes of data.
--- 62.236.221.71 ping statistics --- 10 packets transmitted, 0 received, 100% packet loss, time 8998ms
$ ping -c 1 62.236.221.78 PING 62.236.221.78 (62.236.221.78) 56(84) bytes of data. 64 bytes from 62.236.221.78: icmp_seq=1 ttl=46 time=58.9 ms

Can you confirm the routing on the two boxes - is there anything different? I would also check the routing on the upstream routers - it is possible that one of your ingress/egress routers has a static entry that is causing issues. I would check all the routers that are inside the 62.236.0.0/15 subnet (BGP thinks that these addresses are part of that subnet).
