Issue Details

Router DNS server set to: 94.140.14.49

Expected Behavior

Regular load times with no failed queries.

Actual Behavior

Long load time with commonplace time outs across sites and apps.

Screenshots

No response

Additional Information

Many sites and apps take a large time to load with many timing out and giving me a no domain error only to then resolve seconds later. This time can range from a couple seconds to almost a minute. The route seems to be taking me from ATT all the way to Czechia? This appears to only happen when connected to ATT as I have my Android using DoH with no issues. This issue also took place at another residence with ATT.
