Regions & data centres¶
Cloud Digit operates across three Tier-III data centres within Bangladesh. Every region is BTRC-licensed, BB ICT 4.0 aligned, and connected to BDIX for low-latency domestic egress.
Regions at a glance¶
| Region code | City | Role | BDIX | Tier |
|---|---|---|---|---|
bd-dha-1 | Dhaka | Primary — every service available | ✓ | III |
bd-ctg-1 | Chattogram | Coastal DR, port-proximity | ✓ | III |
bd-syl-1 | Sylhet | NE DR, geographically diverse | ✓ | III |
Why three
The three sites are geographically diverse enough to survive a single-region disaster (cyclone, regional grid, fibre cut) while staying inside Bangladesh — so DR strategies don't break sovereignty.
Picking a region¶
| Driver | Pick |
|---|---|
| Lowest latency to Dhaka users | bd-dha-1 |
| Banking / FI primary site | bd-dha-1 with bd-ctg-1 as DR (most common) |
| Port / shipping / customs | bd-ctg-1 (close to CPA, JICA terminal) |
| Geographic diversity from Dhaka | bd-syl-1 (different grid, different fibre path) |
| Multi-region active/active | All three, behind regional load-balancers |
Service availability matrix¶
The table below tracks which services are GA (✓), in preview (P), or not yet launched (—) per region. It is the source of truth — the per-service pages link back here.

Preview = limited capacity
Services marked P are available on request and may have constrained capacity. Open a ticket through the support portal to request access.
Cross-region¶
- Object Storage replication is supported across all three regions via S3 cross-region replication semantics.
- VPC peering between regions is available; uses the BDIX-anchored backbone, single-digit-millisecond domestic latency.
- Managed databases support cross-region read replicas where the service column above shows GA in both regions.
