Data centres, routing and CDN selection

The nearest server on a map is not always the fastest route for the people who use your site.

Data centres, routing and CDN selection

Editorial verdict

The short answer

Choose location using audience distribution and measured network paths. Then use a CDN for cacheable assets. Do not confuse a CDN point of presence with the origin server or assume a country label proves local infrastructure.

Before you buy

Questions the provider must answer

  1. 01Where is the origin server?
  2. 02Can the location be selected or moved?
  3. 03Where are backups stored?
  4. 04Which CDN locations serve the target audience?
  5. 05Have tests been run from local networks?

Decision process

A practical, repeatable method

1

Map real visitors

Use country and city analytics, not the owner’s location.

2

Shortlist origin regions

For South Asia, compare India, Singapore and relevant local infrastructure where available.

3

Measure from the audience

Run repeated tests from multiple networks and time periods, including uncached dynamic requests.

4

Inspect routing

Traceroutes and time to first byte can reveal inefficient paths that physical distance misses.

5

Add CDN coverage

Cache images, scripts and public pages close to visitors while understanding which dynamic requests still reach origin.

6

Plan resilience

Document backup geography, location migration and recovery options before an outage.

Avoidable errors

Common mistakes

  • × Selecting a server only by kilometres
  • × Calling CDN presence a local data centre
  • × Testing only from Europe or North America
  • × Ignoring dynamic checkout latency
  • × Assuming backups are geographically separate

Frequently asked questions

What buyers ask next

Is Singapore best for all Asian sites?

No. It is a strong regional hub, but measured routing and audience distribution decide.

Can a CDN fix a distant origin?

It helps cacheable content, but uncached application and database work still reaches the origin.

Should the origin be moved later?

Yes when evidence supports it, but confirm migration time, DNS change and rollback.

What is time to first byte?

The delay until the first response byte, influenced by network latency and server processing.

How to use this guide

Separate facts, estimates and judgement.

Provider documentation establishes product terms. Calculations explain their financial effect. Regional suitability requires checkout verification and testing from the intended audience. A recommendation is editorial judgement only after those layers agree.
