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 — March 18, 2026: Cloudflare HTTP 520 Errors Under Investigation

Cloudflare is experiencing an active incident involving increased HTTP 520 errors, specifically affecting HEAD requests. The issue was identified at 09:53 UTC on March 18, and a fix is currently being implemented. Separately, Cloudflare is performing scheduled maintenance at its LAX (Los Angeles) datacenter through March 19 at 00:00 UTC, which may cause slight latency increases for traffic routed through that facility.

All other major cloud and infrastructure providers are reporting normal operations:

AWS: No active incidents

Google Cloud: All services operational

Microsoft Azure: All services operational

OpenAI: All systems operational

GitHub: No reported issues

No new BGP routing incidents have been detected today. The most recent BGP-related events were a Cloudflare BYOIP route withdrawal on February 20 and a route leak on January 22, both of which have been fully resolved.

On the local level, the City of Midland, Texas reported an internet outage affecting some city services on March 17, which may still be ongoing.

Overall, the internet is functioning normally with a minor, limited-scope incident at Cloudflare that is actively being addressed.
