Swisscom RES to Cloudflare DNS - 20% packet drop - swinog

19 Jul 2020


      Hi everyone,
Can someone confirm a similar issue with Cloudflare DNS from Swisscom 
residential network? What's interesting, from Swisscom SME I don't see 
that issue (both connections are in Zurich)... It started on 18th of 
July around 00h30 (CEST).
