Hi everyone, we’ve been big fans of the cloudflare DNS resolvers and use it for all of our I.T. customers, but while diagnosing several internet issues the past few days we noticed that across the board every single one of our customers using Comcast as their ISP (Home & Business) are getting 25% to 40% packet loss to IP 220.127.116.11 and 18.104.22.168. As far as we know, it does appear isolated to Cloudflares dns resolver IPs and I’m unaware if this is affecting Comcast users outside metro Detroit. Traceroute shows the possible problem child being 22.214.171.124 .
I’ve tried reporting this to Comcast technical support and escalating it but I’m sure anyone that has dealt with that knows I’m spinning my wheels. Does anyone have any suggestions?
