From an XP desktop via a linksys box and Verizon DSL to my appliation server, I used to be able to use the pathping command to do a traceroute with packet-dropped rates, per hop.
In the last few weeks, this either stops at my router or all the intermediate hops don't tell me anything.
It looks like Verizon has turned ICMP off. I've not changed anything from my linksys router and upstream
What changed?
