The Headquarters Bias
A test from headquarters tells you about that location. Branch offices, clinics, and distribution centers may reach the same Azure region through very different network paths.
Azure region selection, measured from your sites
Find the best Azure region
for your entire fleet.
RegionProbe measures network performance from your physical locations to candidate Azure regions. Compare performance across participating sites before choosing where to deploy.
Born from a real Azure network deployment spanning approximately 30 sites.
The Enterprise Dilemma
The best region for HQ may not be best for every site
A region choice based on one office can overlook the rest of the network. Measure from the locations your teams depend on before committing to a deployment.
Last-Mile Peering Realities
Nearby does not always mean faster. Site connectivity and routing can make geographic distance a poor substitute for measurements from your network.
Painful Regional Lock-In
Changing regions after deployment can mean revisiting infrastructure, dependencies, and migration plans. Compare the options while that choice is still open.
How RegionProbe Works
Measure locally. Compare the fleet. Choose with evidence.
Site measurements give RegionProbe the context to compare candidate Azure regions across your network. Pilot scope and deployment requirements are agreed before testing.
Site AgentRegionProbeFleet AnalysisRecommendation
STEP 01
Measure from participating sites
Start with the physical locations that matter to your decision. Agree the measurement points and deployment requirements for the pilot.
- Identify participating locations
- Choose candidate Azure regions
- Agree the measurement scope
STEP 02
Compare the network paths
Use site-to-region measurements to compare performance over the periods that matter to your organization, rather than relying on a single office or snapshot.
- Compare candidate regions
- Look for site-level differences
- Include relevant operating hours
STEP 03
Evaluate the fleet-wide trade-offs
Bring the results together to assess regional fit across the fleet. Consider both the overall pattern and locations that need closer attention.
- Review results across locations
- Identify performance trade-offs
- Inform the region decision

Compare three candidate regions across ten fictional sites. This interactive example uses generated values, not live network tests or customer measurements.
Measurement Perspective
Compare the evidence behind your region choice
A guide to measurement approaches, not a performance benchmark. Coverage depends on the tools and sites included.
| Decision question | RegionProbe approach | Manual site checks | Published latency references |
|---|---|---|---|
| Where are measurements taken? | Participating physical sites | The locations you test | The source’s measurement locations |
| How is the fleet considered? | Compare participating sites together | Combine the results you collect | Check coverage against your fleet |
| What decision does it support? | Evaluate candidate Azure regions | Interpret your measurements | Reference context |
| How are results reviewed? | Site-to-region comparison | Your chosen tools and records | Reference context |
| What does setup involve? | Agree scope and requirements for the pilot | Choose hosts and a test method | Review the source and its coverage |
Where Site-Level Evidence Matters
Make location-aware Azure decisions
Multi-Branch Retail & Clinics
Teams choosing a cloud region for applications used across clinics, bank branches, or retail stores, where the experience at each site matters.
Azure Virtual Desktop / Citrix
Teams planning remote desktop deployments and evaluating how candidate regions serve users in different physical locations.
Cloud Architects & MSPs
Advisers comparing regional options and explaining network performance trade-offs to technical and business stakeholders.

RegionProbe Pilot
Request a RegionProbe pilot
Interested in evaluating Azure regions for your network? A pilot starts with a discussion of your locations, candidate regions, and decision criteria, followed by an agreed measurement scope.
A scoped evaluation for your network
Deployment requirements, network access, data handling, and the observation period should be reviewed together before any pilot begins.
Submit your request, then confirm your email to join the pilot list.
Registration records your interest; access and pilot scope are agreed separately.

Frequently Asked Questions
What does RegionProbe help us decide?
RegionProbe compares network performance from participating physical locations to candidate Azure regions. The aim is to find the best regional fit for the fleet while making site-level trade-offs visible.
Why measure from our own sites?
Published references provide useful context. Measurements from your own sites help you compare the network paths your organization actually uses.
How long should a pilot measure performance?
The observation period should cover the operating hours and usage patterns that matter to your fleet. Pilot duration and decision criteria are agreed before drawing conclusions.
What should we review before deployment?
Review participating sites, candidate regions, deployment requirements, network access, and data handling. The pilot discussion establishes what will be measured and how the results will be evaluated.
What happens after I request a pilot?
Confirm your email to register your interest. Your request is the starting point for discussing fit and scope; it does not guarantee access, a start date, or a particular result.
