So when this is happening mtr works but http, ssh and ping don't?
If you run tcpdump on the server, do your http/ssh packets even
reach it?
If you do tcptraceroute on port 22/80/443 from your home, how far
does it get?
Are there any firewall rules in place on your server?
DO you have access to any other host so you can tell if it is just
your home IP that has problems?
Cheers,
