Are you by any chance in one of those countries that are now blocking IPs because of IPTV?
Some countries have used aggressive blocking techniques, which end up affecting legitimate services for a few hours. A few months ago, a block of this kind blocked Google Drive for several hours, it was crazy.
I highly doubt that. But it looks like just rebooting the router has done it for me.
@CCECash I would suggest you guys investigate this further since it doesn't seem like I'm the only one facing this issue.
