Hej,

Enligt dina traceroutes så når du ju slutdestinationen, men som jag förstår så kan du inte göra något uppslag ifall du använder dig av deras tjänst?

Fungerar fint när jag testar detta från både min kontorsdator och hemdator som jag har via a3.s nät, samt får även svar när vi gör försök från en switch i ditt område.
Att det tar två olika vägar till 1.1.1.1 / 1.0.0.1 är inget fel i detta fall.

I och med att du når dem via en tracert, men inte kan göra uppslag hos dem så skulle du behöva ta detta med de ansvariga för tjänsten.
Har du haft någon kontakt med cloudflare?

Med vänlig hälsning,
...
