Quick answer
A good data centre site has at least two physically diverse fibre routes from different carriers, low latency to major internet exchanges and cloud regions, and a practical path to submarine cable landing stations such as Mumbai or Chennai.
Key takeaways
- Route diversity matters more than carrier count
- Check latency to users and cloud regions
- Dark fibre options add flexibility
Route diversity
Two carriers in the same trench is one route. Ask for route maps and make sure paths enter the site from different directions.
Latency targets
Measure round-trip times to the internet exchanges and cloud regions your customers use. Edge sites should be close to end users.
International connectivity
Most of India's submarine cables land in Mumbai and Chennai, so sites with fast paths to those hubs suit global traffic.
