Does Verizon reboot their equipments at 2 am or something? I just don't get how things get clear up after certain time and then get clog up again next day.

It clears up at night because during the day and evening (at peak times) the backbone gets way over taxed. When traffic slows down at night, things appear normal. At least this is what I believe is going on.

Yea, same problem exists on east coast too, not just CA.
Slows down alot at night especially. And for me, it's gotten
a bit better last few days, I can stream, but still erratic
download speeds. I did notice the routing 2 hops out from
me changed in last couple days, but core problem still there.

Funny thing, I have an open case on this and a very nice support
person calls me every day to see how things are doing. I
repeat that this is in their network or CO, not at my house
(please don't send another tech!). Have sent him the
traceroutes and explanations via email. I told him, I want
him to call the local manager and get me an answer about
what they think it is - but so far nothing. I just wanted
them to say anything, but get zero response. Network
Techs say it's all fine...(they told me that once). He'll
call tonight and ask me if I have heard anything more about
this problem!

It's either bad routing or over-subscription or both.
I do get decent performance in general, but there are
sites that either hang or I download a PDF and get 1MB/s
- this should not be (where I did not have this with Comcast).

FYI - if you are interested, lob and email to the following
address and yell, this is what I got from the support person.
Change first 2 letters to your state abbrev.

Email: pa.fsc.customer.experience@verizon.com

Go ahead try that, opening a case with support is a total
waste of time. Not only will nothing ever get fixed by that,
it just wastes everybody's time.
