If you've landed on dual.part-0017.t-0009.fb-t-msedge.net, you're probably not looking at a website intended for public use. Our analysis shows this is a subdomain of Microsoft's msedge.net domain, but the specific address is broken: the SSL certificate doesn't match, and the server returns a 404 error with an Azure Front Door configuration message. This is typical of a misconfigured or decommissioned internal endpoint, not a scam or fake site. Legitimate Microsoft infrastructure services normally have valid certificates and working pages. There are no signs of phishing or malware, but the technical failures mean you can't use this URL for anything. If you were expecting to access a service here, double-check the address or contact Azure support through proper channels. For most people, the best advice is to ignore this URL entirely — it's a dead end, not a threat.
No — dual.part-0017.t-0009.fb-t-msedge.net doesn't look safe
In plain English
This domain doesn't host a working website. It's a misconfigured Azure Front Door endpoint that returns a 404 and has an invalid SSL certificate. Unless you're a Microsoft system administrator troubleshooting internal infrastructure, there's no reason to trust or use this address.
What you should do now
Don't panic. These steps limit the damage, and the sooner you take them the better.
Don't enter any details
No passwords, card numbers or personal information — even if the site looks professional.
Close the tab
Especially if you got here from an email, text message or social media ad.
Already paid? Call your bank
Contact your bank or card provider right away. They can often stop or reverse a recent payment.
Warn others
Report the site and share this check with anyone who sent you the link.
Where the score comes from
The SSL certificate is invalid for this domain and the site is unreachable due to a TLS error. Any legitimate service, even internal infrastructure, needs a valid certificate to be trusted.
This is a subdomain of msedge.net, a domain owned by Microsoft Corporation. The ownership chain is clear and reputable, even though the specific subdomain isn't registered separately.
No blacklist hits, no threats detected by Google Web Risk. The domain has a clean history and is hosted on Microsoft's own network.
Contact information is present, pointing to Azure support. While there's no about page or social media, that's normal for a technical backend endpoint. The page text explains it's an Azure Front Door configuration.
Missing privacy policy and terms of service are expected for a non-commercial infrastructure URL. This isn't a store or service collecting user data.
DNS resolution works and hosting is on Microsoft's reliable network, but the SSL certificate mismatch and lack of security headers make the setup unreliable. The 404 status confirms the service isn't properly configured.
