I am having 100% packet loss at alter.net.
Exactly the same problem as:
I need to know if Verizon has fixed their hardware & software, & what I need to do?

That trace route you posted looks completely normal.
Many servers are configured not to respond to ping packets. I have my FiOS router set to not respond to ping packets. If you tracert to my WAN IP address it will show 100% packet loss, could not be reached, etc. Yet all use of the Internet is normal from here.
The bottom line on the tracert you posted is at step 12 the total latency is very low. That means your ping packets are taking no more than 19 ms worst case, and less than that on average. There can't be any significant delay happening at step 6.
There's no problem with that routing.

Synopsis of Tracing a path from Boston to California:
Hops locally to Major city (Boston)
Jumps to New York.
Bounces around in New York 6 times (Verizon throttling?)
At hop #10, exits verizon system (all alter.net entries are Verizon).
Verizon technician said "verizon has no control after hop 5" (right before 100% packet loss @hop 6).

Pingplotter program reveals 100% packet loss at hop #6.
Why is hop #6 hidden?
How do I find more information about this server?

that isn't packet loss. Packets can't regenerate themselves if they are dropped. They are either dropped or not dropped.
The fact that it passes that router and continues uninterrupted to all the remaining hops shows you that it's not dropped. That router simply doesn't respond to trace's or pings. They were programmed not to.
This is a good website that shows you how to analyze that trace and other trace's properly.

100% loss that does not carry onto any further hops means that the router or device at hop 6 is simply programmed to not respond to ICMP or UDP Echo requests. This is usually to save CPU power on the gear for handing other requests.
