Remove `DNS.WATCH`?

The chance to got a ;; connection timed out; no servers could be reached message from the dig command when using DNS.WATCH is pretty high, about 15% chance from my test results, maybe it's not a global issue, but it at least happens in Asia, should consider to remove it.

Currently, 84.200.69.80 is the IP we are using to query DNS.WATCH(resolver1.dns.watch), after done some additional tests from multiple locations, that I can confirm 84.200.70.40(resolver2.dns.watch) is "a little bit" more reliable than the one we are using, less than half of the chance to time out, though it may be strange, but looks like we can switch to the alternative resolver for now.

Still facing too many timeout requests, trying to replace it with https://www.dns0.eu/open

If you @PeterDaveHello are interested in some DNS-ping monitoring data/statistics you may have kindly look at my DNS-ping monitoring repos/sites made with ❤️

If you have some more interesting DNS resolvers to be added - tell me 👍🏼

Feel free to add dnslow.me if it supports encrypted DNS ;)

I'm sorry, but I didn't get it working (not timeouting) 😞
