Check from every region

Run an HTTP(S) check from 95+ regions across AWS, GCP and Azure at once and see exactly who's slow and who's failing — with fastest/slowest and a per-provider breakdown.

  • 95+ regions · 3 clouds
  • Fastest & slowest by region
  • Resolved IPs per region

The full request, broken down

Not just up or down. Every check breaks the response into DNS resolution, TCP connection time, TLS handshake, and time to first byte — per region — plus the TLS certificate, CDN cache state, and redirects.

  • DNS → TCP → TLS → TTFB waterfall
  • TLS certificate & expiry
  • CDN cache & redirects
Expanded region detail showing a DNS, TCP connection, TLS handshake, and time-to-first-byte waterfall alongside the full TLS certificate.

Monitor & get alerted

Turn any check into a scheduled monitor. RegionCheck watches it around the clock and alerts you — by email, Slack, Teams, PagerDuty, or webhook — the moment it fails or a certificate nears expiry.

  • SSL-expiry & assertion alerts
Alerting configuration dialog with notification channels, alert-on-redirect, SSL-expiry, and assertion options.

Status pages & sharing

Show the world you're up. Publish a public status page backed by your real checks, embed it anywhere, and share any result by URL.

  • Public status pages
  • Embeddable widget
  • Shareable result URLs

Three ways to use it

Web UI

Run a check and read scannable, region-by-region results in your browser.

HTTP API

Drive every check from scripts and CI with stable, structured JSON responses.

MCP server

Let AI agents run the same checks through the Model Context Protocol — full feature parity.

Who it's for

Built for SREs, platform & DevOps engineers, network engineers, and founders debugging regional issues.

Frequently asked questions

What is RegionCheck?
RegionCheck runs an HTTP(S) check against your target from cloud regions worldwide, so you can see how your infrastructure actually behaves from everywhere at once instead of just from your own network.
What does a check measure?
One HTTP(S) request per region, broken down into DNS resolution, TCP connection time, TLS handshake, and time to first byte — plus the TLS certificate, resolved IPs, CDN cache state, and redirects. Every field is shown region by region with raw detail you can expand.
Which clouds and regions does it run from?
Checks execute from workers deployed across 95+ regions on AWS, GCP, and Azure, giving you many independent vantage points across three providers.
Is there a free tier, and do I need an account?
You can run public checks without an account, subject to rate limits. A free account lets you save checks, keep run history, and use the API and MCP server.
Can I monitor and get alerted?
Yes. Any check can become a scheduled check that runs on a recurring schedule, detects incidents, alerts you by email, Slack, Teams, PagerDuty, or webhook, and can power a public status page.
Can I use it from an API or an AI agent?
Yes. The HTTP API and the MCP server expose the same checks as the web UI, so scripts, CI, and AI agents can run and read checks at full feature parity.
