I notificed, that my mirror's error log contains name resolution errors. Mirror: https://archlinux.org/mirrors/kyberorg.fi/ 

Error is: Name or service not known (HTTP/HTTPS) and same for RSync:

rsync: getaddrinfo: rsync.kyberorg.fi 873: Name or service not known
rsync error: error in socket IO (code 10) at clientserver.c(139) [Receiver=3.2.7]

All those errors occurred  within two (or same) German servers:

49.12.124.107
2a01:4f8:242:5614::2

Does anyone have the same issues with this server?
