Russia would be able to hijack DNS requests inside the country, and keep .ru resolution working for Russian citizens. Currently a Russian entity is managing the delegated name servers for the .ru ccTL

DNS is not my strength, but I'm a little confused here.

I realize there are solutions for adding a bit of resiliency by doing things at the DNS level (auto failover, etc), but not all clients are using DNS providers that have those sort of capabilities bui

* A couple bugs while issuing wildcard certificate if you don't control the full DNS: https://github.com/go-acme/lego/issues/1597

I signed up for a new account yesterday. Your DNS sync is failing. Created a ticket and 24 hours later still no response.

And once you get to dns.pt to manage it.... pff!

Good find! I relied on DB-level verification, but better to check before making DNS changes. Now updated to also give a nicer error message. Thanks!

I'm sure his domains are real countries, not DNS (Image)

A few minute usually. If you use Cloudflare proxying, I'd disable that first or make sure DNS validation works with it. Currently I see a few domains failing because of CF settings. Feel free to PM me

Currently, I set the TTL on GG cloud dns to 1 day so Cloudflare can cache dns better. If anything happens then I can easily change the record in Cloudflare to other backup IP or CNAME.

That's quite reasonable. Can I ask why you are doing the cloudflare + google dns setup instead of just using cloudflare load balancing? Is it to save costs?

I will use another domain domain_b.com at Google Cloud DNS and domain_a.com at Cloudflare. Domain_b is configured as geo routing so it will returm the nearest IP for each request. Domain_a.com is conf

I tried to search for more info and found this: https://cloud.google.com/blog/products/networking/dns-routing-policies-for-geo-location--weighted-round-robin

If DNS only then any geodns is ok. I am using Google Cloud DNS. Amazon Route 53 is popular choice too. They are pay as you go model so the cost is based on number of queries

Do you really need anycast IP? Geo DNS is very different but cheaper
