This is an official response from Guild Wars 2 that i recieved from their support.
Our network team has been investigating this issue and has confirmed that the issue is not due to any issue on our side. In our opinion, the root of the problem is most likely at Verizon FIOS end, especially since we have been getting similar reports from other players using the Verizon FIOS network.
Our suggestion would be to try bypassing your ISP's provided DNS servers and instead, use the following instructions so your computer connects to the Google public DNS system:
Using Google Public DNS

Regardless of if this helps, we urge you to report the issue to your ISP directly. Generally the more of these reports an ISP receives, the quicker they will address the issue. Additionally, players have provided some workarounds in the reddit thread and forum posts linked below that may be of use. Please be aware that player provided workarounds are not endorsed by Arenanet or NCSOFT and using them will be at your own risk.

Well, I tried the DNS thing during the peak hours 7pm to 12am, when I had to download the patch, and it didn't work. I hope that some verizon tech can answer this problem for me, so that the next time I have to download during primetime, I won't have to wait.
