STT GDC Bengaluru 1 is 0.6 MW — six hundred kilowatts. It is the second smallest data centre record in this registry, behind a 0.5 MW edge site in Patna. It is also 2.6% of a 23 MW city headline that gets quoted in market notes as Bengaluru capacity. No stage, rack count, floor area or PUE is published. Keep the record — it is a real site and its existence is a fact about the market. But a six-hundred-kilowatt suite is not what anyone means when they say a data centre, and the gap between the two is the whole argument of this page.

2What six hundred kilowatts is
Six hundred kilowatts is one enterprise customer with redundancy, or a network point of presence with some compute attached.
| Assumed density | Cabinets | What it looks like |
|---|---|---|
| 5 kW a rack | 120 | a small hall, one or two rows |
| 8 kW a rack | 75 | a single contained aisle |
| 12 kW a rack | 50 | one row of dense compute |
At this size the building cannot host a second tenant without splitting the suite, cannot offer meaningful expansion, and would struggle to justify its own substation. It exists because it was cheap to keep, or because a specific customer is anchored to it, or because it holds connectivity that is worth more than the compute.
Those are all legitimate reasons. None of them make it capacity.
3The small end of the registry
Five records in this registry sit under one megawatt, across four operators and five cities. Together they are 2.7 MW — 0.1% of the total.
| Record | MW | Why it is in the file |
|---|---|---|
| STT Delhi 1 | 0.9 | a city suite, part of a 12 MW Delhi headline |
| STT Bengaluru 1 | 0.6 | part of a 23 MW headline that reconciles to rounding |
| CtrlS Patna Edge DC 1 | 0.5 | the first edge site in Bihar, recorded separately from the larger Patna building |
| Sify Vashi | 0.38 | legacy Mumbai node in the original data centre corridor |
| NTT Mumbai BSE Data Center | 0.3 | an exchange-adjacent site, where latency is the product |
| Total | 2.7 | 0.1% of the registry’s counted capacity |
Two of the five are published by NTT and Sify as separate facilities, and three are children inside city headlines. That inconsistency is the interesting part: the same size of site is a record for one operator and a rounding detail for another.
Gridvik keeps all five, because deleting them would lose the fact that the operator runs them — and because the alternative, quietly rounding them away, is how market totals end up not matching any primary source.

5Limits and open questions
- Nothing but a capacity. No stage, racks, floor area or PUE.
- Single source. No directory lists a 0.6 MW STT Bengaluru site separately.
- Purpose unknown. Connectivity anchor, legacy tenant or leased site awaiting redevelopment — the public record does not say.
- Counted inside a headline. The 0.6 MW is part of the 23 MW that gets quoted, and is 2.6% of it.
- What would close it. One line from the operator. This is the cheapest record in the file to complete.
