Short answer: Factories and plants in Malaysian industrial parks use Dedicated Internet Access (DIA) when production, ERP, remote monitoring and supplier systems cannot run on shared broadband. Plan earlier than you would for an office: where new fibre has to be laid, installation typically takes about 8 to 16 weeks, and sometimes longer in industrial areas. Confirm which carriers already reach your site, decide what must keep running during an outage, and scope any backup line and private site-to-site links in the same project.

Why factories move from broadband to DIA
Business broadband is shared, usually faster on download than upload, and best-effort with no uptime guarantee. DIA is a dedicated (1:1), symmetrical line backed by an SLA (see DIA vs business broadband). For a plant, that difference shows up in a few places:
- Cloud ERP, MES and inventory systems that stop orders or shipments when the line drops.
- Upload-heavy traffic such as CCTV viewed offsite, cloud backups, file transfer to head office and video calls with overseas teams.
- Remote access for equipment vendors, IT support and head office, which usually needs a fixed public IP address.
- Supplier, customer and bank systems that only accept traffic from allowlisted IP addresses.
Industrial sites: what is different
| Factor | What to check |
|---|---|
| Fibre reach | Many industrial lots are further from existing carrier fibre than city office towers. Ask each carrier whether your lot is already on its network for the bandwidth you want. |
| Lead time | On-net sites typically go live in about 4 to 6 weeks from order. Where new fibre is needed, plan for about 8 to 16 weeks, and sometimes longer in industrial areas (see our DIA installation timeline checklist). |
| Building entry and cable route | The carrier needs a route from the road to your comms room. Large compounds, guardhouses and long internal cable runs add survey and build steps. |
| Comms room, rack and power | Keep the router and fibre termination away from dust, heat and vibration on the production floor. Prepare rack space, power and earthing before the install date. |
| Site access | Safety inductions, permits or fixed access windows can delay surveys. Tell the carrier about access rules early. |
Planning checklist for a factory DIA line
- List what runs over the internet line. ERP, email and Microsoft 365, video calls, VPN users, cloud backups, CCTV and vendor remote access. Size from peak use, not headcount (see our DIA bandwidth sizing guide).
- Separate internet traffic from private traffic. If the plant shares ERP or file servers with head office or a warehouse, that traffic can run on a Metro Ethernet or leased line link instead of the internet line.
- Decide what must keep running during an outage. Then choose the backup: DIA plus business broadband failover on the same router, or two DIA lines from different carriers for the highest resilience (see near-zero downtime options).
- Count the static IPs you need. DIA includes a static IP, and more can be requested. Remote access, CCTV recorders and allowlists are the usual reasons (see static IPs with DIA).
- Compare carriers for your exact lot. Coverage differs from one industrial park to the next. Ask for written offers from at least three Tier-1 carriers (see DIA carriers compared).
- Read the SLA before you sign. Check the availability target, repair commitment, exclusions and service credits. Our DIA SLA guide lists what to ask.
- Book the survey early. Share the full address, lot number, comms room location and access rules with your order so the survey and any fibre build can start straight away.
Common mistakes on industrial DIA projects
- Ordering the line a few weeks before production starts, then waiting on new fibre
- Putting the router on the production floor with no proper rack, power or cooling
- Adding a backup line after go-live instead of scoping it at quote stage
- Running site-to-site ERP traffic over the internet line and sizing it too small
- Forgetting to update vendor and partner allowlists when IP addresses change

Frequently asked questions
How long does DIA installation take for a factory in Malaysia?
If the carrier’s fibre already reaches your site, typically about 4 to 6 weeks from order to live. Where new fibre must be laid, about 8 to 16 weeks, and sometimes longer in industrial areas.
Can I have a backup line at my factory?
Yes. A common setup is DIA plus business broadband failover on the same router, or two DIA lines from different carriers for the highest resilience. Scope the backup at quote stage.
Do I need a static IP for remote access to factory systems?
Usually yes. Vendor remote access, CCTV viewing and partner allowlists need a fixed address. DIA includes a static IP, and more fixed IP addresses can be requested.
Should factory-to-head-office traffic run over DIA?
Not always. Private traffic between your own sites can run on a Metro Ethernet or leased line link, so the DIA line only carries internet traffic.
Which carriers does DACS work with?
TM, Maxis, TIME and uMobile. Coverage depends on your exact lot, so we compare written offers for your site.
