DNS for #dc09ru is now hosted by desec.io, a fully FOSS service operated by a non-profit organization.

I'm going to re-enable DNSSEC tomorrow to be sure that all resolvers updated their caches.

(Also, i hope ACME dns-01 challenge will work with the deSEC's certbot plugin, as there were some problems when my friend tried to setup it)

deSEC – Free Secure DNS

@darkcat09 I tried many such DNS hostings (desec.io, 1984.hosting, FreeDNS, etc.), and in the end, the 1984.hosting looks the best. desec.io is still good (2nd/3rd place) though. Anyway, I just suggest you try it too.
