It appears the website for KU Leuven (kuleuven.be), a major Belgian university, cannot be resolved using 126.96.36.199 or 188.8.131.52 even after flushing the DNS cache at https://184.108.40.206/purge-cache/
Both staff and students are affected by this.
dig @220.127.116.11 +short kuleuven.be
Yields no results
dig @18.104.22.168 +short kuleuven.be
But with Google’s DNS, it works fine.
Submitting the domain name at https://22.214.171.124/purge-cache/ doesn’t help either.
Can someone please take a look?
This issue also affects subdomains like idp.kuleuven.be for example.
