Hi, @sumhm. I do see the custom domain is not being served by Netlify. Some other service is being used to proxy to us. The IP address used is one for StackPath.
$ whois "$(dig publications.bii.a-star.edu.sg A +short | tail -n 1)" | grep "OrgName"
OrgName: StackPath, LLC.
The DNS records also confirm this:
$ dig publications.bii.a-star.edu.sg +noall +answer
; <<>> DiG 9.10.6 <<>> publications.bii.a-star.edu.sg +noall +answer
;; global options: +cmd
publications.bii.a-star.edu.sg. 250 IN CNAME t3s2j2y6.stackpathcdn.com.
t3s2j2y6.stackpathcdn.com. 550 IN A 151.139.128.11
Note, we do not recommend proxying to our CDN.
That being said, if you are seeing incorrect content served, please let us know the x-nf-request-id
header for the incorrect response and we can research this further. There is more information about how to find that header here:
If there are other questions or if there is a header we can research, please let us know.
