I would look at using mtr, it is usually much more accurate than plain old traceroute. I would use mtr to track down latency or packet loss issues (i.e. find the hop that is the problem).
Also it is important to note that that just because a traceroute or ping fails, this does not mean that the service you are interested in is also down. You really need to use a variety of tools to sort out these kinds of issues (hping, "openssl s_client", and nmap are really handy). These days with load balancers, content delivery networks, and all sorts of security appliances, it can be really challenging to know exactly what is going on. Hth, If you have control over both ends netcat (or the more modern ncat) is really useful to verify connectivity.
