Custom domain (getfilterkey.com) intermittently times out / serves wrong content despite correct DNS config

Domain: getfilterkey.com Netlify project: wonderful-malabi-6f37cc Added to Netlify: Sep 9, 2026 (via Namecheap) Issue: my page intermittently returns ERR_CONNECTION_TIMED_OUT, and when it does resolve, sometimes shows unrelated content instead of my site. The project’s own netlify.app subdomain (wonderful-malabi-6f37cc.netlify.app) loads correctly every time, so the site/build itself is fine — this looks like a DNS/edge issue specific to the custom domain. What I’ve already verified as correct: - Namecheap nameservers are set to Custom DNS: dns1-4.p06.nsone.net (matches Netlify DNS exactly) - Namecheap’s Parking Page setting is OFF, and Domain/Email redirect features aren’t even enabled (they require Namecheap’s own nameservers, which aren’t in use) - Netlify’s DNS zone for getfilterkey.com shows the correct NETLIFY alias record pointing to wonderful-malabi-6f37cc.netlify.app, same for www.getfilterkey.com - SSL certificate (Let’s Encrypt) shows as valid, covering *.getfilterkey.com and getfilterkey.com - netlifystatus.com shows all systems operational, no incidents A global DNS check shows inconsistent results across resolvers worldwide — different regions return different IP addresses for the A record, and several resolver locations fail to resolve it at all. Could someone take a look at the DNS zone health for this specific domain? Happy to provide any additional diagnostic info needed.
