I’ve had reports from users in Switzerland using the salt.ch network that my domain (songwhip.com) is unreachable. They see the page loading indefinitely. The same users can reach the site when on devices using different mobile network provider (Swisscom), also when their device is connected to wifi they can reach the site fine.
This seems like a DNS issue as it affects all pages under the domain. Would anyone be able to help me to diagnose this issue?
