How do I check if my internet is working?

Visit isinternetup.com — if you can see the page, your internet is working. The site also runs diagnostics including DNS resolution, latency, speed tests, and more to give you a full picture of your connection health.

What is a WebRTC leak test?

A WebRTC leak test checks if your real IP address is exposed through your browser's WebRTC feature, even when using a VPN. This is important for privacy — if WebRTC leaks your local IP, websites can see your real address despite VPN protection.

How can I tell if my VPN is working?

The VPN Detection Hint compares your browser's geolocation with the location your IP address reports. If these are far apart (more than 100 km), it suggests a VPN or proxy is active. A match means your reported location is consistent.

What is my IP address?

Your IP address is displayed automatically when you visit isinternetup.com. The site detects whether you're using IPv4 or IPv6 and shows your approximate location based on your IP.

What TLS version is my browser using?

isinternetup.com detects and displays your TLS version automatically. Modern browsers typically use TLS 1.3 with HTTP/2 or HTTP/3. TLS 1.3 provides the best security and performance.

Internet Status — April 13, 2026: Incidents Detected

Overall, the internet is functioning normally today with one notable incident.

OpenAI API is experiencing elevated 401 authentication errors across its API endpoints. The issue has been ongoing for approximately 16 hours as of 1:38 PM UTC. OpenAI has identified the problem and is working on implementing a mitigation. Users relying on OpenAI API integrations may encounter authorization failures. Other OpenAI services including Codex and Sora appear unaffected.

Cloudflare is conducting scheduled maintenance at its St. Louis (STL) data center through 15:00 UTC today, which may cause slight latency increases for users routed through that location. Additional maintenance windows are planned for Santiago, Amsterdam, Osaka, and Frankfurt over the coming days. Some Cloudflare edge locations in smaller markets across Africa, Asia, Europe, and Latin America are reporting partial outages, which is typical for edge network operations.

All major cloud providers are reporting normal operations:

Google Cloud: No incidents, all services operational

Microsoft Azure: All services operational, no active events

AWS: No widespread issues reported

No BGP routing incidents, DNS failures, or undersea cable issues have been reported today.

Recent resolved incident: On April 2, Microsoft 365 experienced a brief global disruption affecting access to office.com and the admin center, lasting approximately 74 minutes before full restoration.

The internet is up.
