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 21, 2026: Minor Incidents, No Widespread Outage

The global internet is broadly operational today. No major cross-provider outages are in progress, though a handful of smaller incidents and scheduled maintenance windows are being tracked.

Cloudflare is running scheduled maintenance at its Seattle (SEA) and St. Louis (STL) data centers through mid-day UTC, with brief latency increases possible as traffic reroutes. Cloudflare Sites and Zero Trust are currently showing degraded performance, and Cloudflare WARP is in monitoring after a connectivity issue that ended at 06:45 UTC on April 20. See https://www.cloudflarestatus.com for live updates.

AWS is showing a limited, regional operational issue affecting AWS Cloud Map, Amazon ElastiCache, and the AWS Management Console in the UAE region; the rest of AWS is reported operational. Google Cloud, Microsoft Azure, GitHub, and OpenAI all report no active incidents at this time.

Recently resolved (past 72 hours): AWS experienced a significant multi-service operational issue centered on a DNS failure on April 18 that briefly disrupted traffic for a number of global services. AWS has since restored normal operations.

Overall: the internet is up, with minor localized incidents worth monitoring but no widespread disruption.
