Multi-Region Website Monitoring
A single monitoring location gives you a single point of failure in your alerting. Sentinel checks every site from four regions across four continents, eliminating false positives and detecting regional outages that single-location monitors miss entirely.
How It Works
Verified from multiple regions before we alert you
Every uptime check runs simultaneously from our four monitoring regions: Ashburn (US East), Portland (US West), Nuremberg (Europe), and Singapore (Asia Pacific). When one region detects a failure, the other regions immediately verify the issue before any alert is sent.
This multi-region verification is what separates reliable monitoring from noisy monitoring. Network blips, transient routing issues, and brief DNS hiccups in a single data center will not trigger a false alert. Your on-call team only gets woken up when there is a real problem affecting real users. And when the issue is regional, Sentinel tells you exactly which regions are affected.
- Simultaneous checks from 4 global regions
- Cross-region verification eliminates false positives
- Regional vs. global outage classification in every incident
Features
Reliable alerting through global verification
4 Global Regions
Monitoring from Ashburn VA (US East), Portland OR (US West), Nuremberg Germany (Europe), and Singapore (Asia Pacific). True global coverage across four continents.
False Positive Elimination
A site is only marked as down after verification from multiple regions. A network blip in one data center will not trigger an alert or wake your on-call team at 3am.
Regional Outage Detection
Know instantly whether an issue is global or isolated to a specific region. If your site is down in Europe but up in North America, Sentinel tells you exactly that.
CDN Verification
Verify your CDN serves content correctly from every edge location. Catch regional CDN misconfigurations, expired edge caches, and routing issues before your users hit them.
