As reported here, accessing the root-domain for kolkata is redirecting to a incorrect URL, this happens as a duplicate 2025 site was accidentally created with a space after it:

$ curl -I https://kolkata.wordcamp.org/
HTTP/1.1 302 Found
....
Location: https://kolkata.wordcamp.org/2025/%20/

After this change, it correctly references the non-deleted site:

$ curl -I https://kolkata.wordcamp.org/
HTTP/1.1 302 Found
...
Location: https://kolkata.wordcamp.org/2025/

Notes

• Some deleted sites (deleted = 1) are also public (public=1)
• Some not-public sites are not-deleted (for example testing.wordcamp.org)
• There's also archived, which are a mix of public=0 and deleted=1

That's why I've included both public and deleted here, which seems to cover the correct subset of sites that shouldn't be redirected to.
