This morning I was unable to resolve imgur.com (web browsers, nslookup, everything).
I disabled my phone's wifi and was able to load the website without issue.
I double checked on downforeveryoneorjustme.com before going further.
I set my PC's DNS to 4.2.2.2 and 8.8.8.8 and I was able to resolve the website immediately.
My actiontec was getting the following for DNS servers from DHCP before I manually configured the aformentioned public servers:
68.237.161.12
71.250.0.12
edit: forgot about the down for everyone website
