DNS servers of a major internet provider in the Czech Republic are down now. Probably not a coincidence (other DNS server's stats show increased traffic so my guess is that Vodafone's DNS servers were unable to cope with the increased traffic and crashed https://twitter.com/BlazejKrajnak/status/1445063232486531099).
It's crazy that half the country doesn't have internet because Facebook stopped working.
