In my post yesterday I stated that at some time yesterday morning all my home machines, wired and wi-fi, were suddenly unable to access dslreports.com, whether by name or IP address. Ping and trace route also fail. I have been able to access non-dslr sites without problem. By cellular I can reach and login to dslr. WhatismyIPaddress.com states that my IP address (47.149.xxx.xxx) is blacklisted by dnsbl.spfbl.net. I reset our router to factory defaults, no luck. Any advice?
