I know neither site is down and can confirm no device can reach the sites through my FiOS connection. These same devices have zero problems when used on another Internet connection (laptops and cell phones).
If you can get to the site through the megaproxy above, then your ip is being blocked.
Do the following again but make sure after hitting release to disconnect the power and leave disconnect for AT LEAST 5 minutes, maybe even more.
Actiontec MI424-WR 1 Click on MY NETWORK icon at the top. 2 Select NETWORK CONNECTIONS from the menu on the left. 3 Select BROADBAND CONNECTION (coax or ethernet) depending on your connection to the ONT. 4 Click SETTINGS 5 Click RELEASE 6 Click APPLY 7 Disconnect the router immediately to prevent it from re-requesting a DHCP lease.
Leave it disconnected for AT LEAST 5 minutes preferably 10 and then reconnect it.
