I have used DNS.watch’s DNS servers for the past few years and was fairly happy with the results, right up until they had a full-scale service outage (see this for the best Tweet about it https://twitter.com/joergmattiello/status/960181757143371778), that crippled my entire infrastructure, for a few days. The response to the outage was less than impressive - I still don’t know what went wrong, how they fixed it, or if it could happen again. I didn’t really like not being able to talk with the provider, not even a Twitter account, AFAIK.
I am a CloudFlare customer, hosting domains and protecting my websites, both as a personal user and as a business user. The FREE services are perfect for my very small usage and fit my wallet.
The reason that I moved from DW (18.104.22.168, 22.214.171.124), to CF (126.96.36.199, 188.8.131.52) is to strengthen that customer relationship, but more importantly, to move to a DNS-over-TLS service (I don’t believe anybody has the right to track and record my every move - however law-abiding I am - what if searching for cat videos becomes illegal in the dystopian future and our overlords can search my DNS queries for retrospective transgressions - I’d be borked!).
However, this is moot, as I have been experiencing problems on my home/test network, where my TV cannot play videos on Amazon Prime Video, or Netflix - as soon as I moved back from CF to DW, problem resolved. If they resolve (LOL) the issues, then I’ll be back.
