Hello everyone,
Good news!
I just got off the phone with a tech support agent at Verizon. After giving him a bit of a hard time and apologizing for it — after being frustrated for the past month over the issues with YouTube and other streaming services — I finally have received word that this issue is officially acknolwedged by Verzion.
The explanation I received is that there is a capacity problem with YouTube/Google services during peak Internet hours — although I actually notice issues during off-peak Internet hours as well — and that they are currently working to address this problem. Additionally, the support technician acknolwedged that there is capacity problems with other services, some of which I have noted in my reporting to Verzion's support. It was stated that they are currently working to add additional capacity.
I'm relieved that someone at Verizon has finally acknowledged that this is, in fact, a serious issue, and that they have said that they are working to resolve it. So, again that's the good news.
And then the bad news: there's no official timeframe for resolution.
If anyone hears anything different, please let me and everyone else know, as I'm eager to have this issue resolved and to finally enjoy the Internet as I had hoped to experience it when I switched to FiOS.
P.S. I would just like to add that the suggestion of blocking certain servers/addresses did not work for me to any great extent. I spent hours trying to block certain IP ranges with not so good results. The end result was frustration, and it mostly resulted in me not being able to play certain videos at all. I've resorted to using a VPN until the issue is fully resolved.
