DNS not working for certain sites all of a sudden
nslookup for netflix.com DNS request times out. This just started within last 48 hours.
Called Comcast Business support - no help.
rebooted comcast bridge and pfsense router - no help
cleared all browser data all browsers - no help
Comcast says all network status is as normal.
IF I use my VPN service, netflix.com and nslookup for netflix.com works fine.
Could there have been a recent server upgrade or security edge upgrade that is inadvertently blocking netflix?
Where else do I look?
