Our data centres in India: Mumbai BOM-1 and Delhi NCR DEL-1

Which region should you pick?

If most of your visitors are in Delhi, Noida, Gurugram, Jaipur, Lucknow, Kanpur, Agra or Chandigarh, choose DEL-1. If they are in Mumbai, Pune, Ahmedabad, Surat, Hyderabad, Bangalore or Chennai, choose BOM-1. When your audience is split, BOM-1 is the safer default — it has the strongest peering and the lowest average latency across the country.

Prices are identical in both regions, with no city surcharge, so the choice is only about where your users are. For Kolkata and the east, where we have no region, BOM-1 usually wins and DEL-1 is sometimes shorter depending on your carrier, so we test both with you before you commit.

There is no southern region. Bangalore, Chennai, Hyderabad, Coimbatore and Kochi are served from Mumbai. For a cached website that gap is hard to feel; for a latency-bound job in the south, such as Remote Desktop for a team in Bangalore or a game server whose players are mostly southern, a host with servers in Bangalore or Chennai will serve you better than we will. Our note on hosting the south from Mumbai sets out what the gap costs, city by city.

For comparison, a server in Singapore is typically 55–70 ms from Indian cities and one on the US East coast 220–260 ms, and in both cases your data leaves India.

What is in each facility

• Tier III design: N+1 power with dual utility feeds, diesel generators and UPS; N+1 precision cooling.
• Multi-homed transit with domestic and international carriers, plus peering at NIXI.
• Biometric access control, 24×7 on-site security and CCTV with recorded retention.
• Always-on DDoS scrubbing in front of every customer port.
• 10 Gbps uplink per compute node, with private VLANs available between your own servers.

Data residency and Indian law

Services ordered in BOM-1 and DEL-1 keep customer data inside India, which matters for organisations subject to RBI, IRDAI or government procurement rules, and simplifies compliance under the DPDP Act, 2023. Our privacy policy sets out exactly what leaves the country and why.

These are typical ranges on wired broadband, not promises; your ISP and the route your carrier picks move them, and the SLA is what we commit to.

Nearby cities follow the same region. From DEL-1: Greater Noida, Ghaziabad and Indirapuram alongside Noida, and Ajmer, Udaipur and Jodhpur alongside Jaipur. From BOM-1: Pimpri-Chinchwad, Nashik and Aurangabad alongside Pune; Gandhinagar, Surat, Vadodara and Rajkot alongside Ahmedabad; Mysuru and Hubli alongside Bangalore; Coimbatore, Madurai and Puducherry alongside Chennai; Secunderabad, Warangal and Vijayawada alongside Hyderabad; and Howrah, Siliguri, Durgapur and Bhubaneswar alongside Kolkata.

Not listed? Every Indian city is served from one of these regions — call +91 75994 50220 and we will tell you which one measures best from yours, and move you free if the answer changes.

Or measure it yourself: our latency test times your browser's round trip to BOM-1 against AWS Mumbai, Singapore, London and Virginia. DNS lookups happen before that round trip even starts; our guide to the best DNS for India shows how to time resolvers from your own connection.

DEL-1 is not in the latency test yet. From a terminal, you can time BOM-1 directly:

curl -o /dev/null -s -w "%{time_connect}s connect, %{time_starttransfer}s first byte\n" https://bom1.bigdomainhost.com/ping.txt

Wi-Fi and mobile data add 5–40 ms over a wired line, and a VPN routes you through its own exit first. If BOM-1 reads much higher than AWS Mumbai, send your ISP and city to support@bigdomainhost.com; that is a routing problem we can report.
