If two Fibre plans offer the same 500Mbps speed, they can still perform differently because the network underneath the ISP may not be the same. In Malaysia, one important distinction is whether your ISP is using TM’s HSBA wholesale network, its own Fibre infrastructure, or another open-access network such as Allo.

The difference matters most when you look beyond the advertised Mbps.

TM HSBA: What Does “Wholesale Fibre” Actually Mean?

HSBA (High-Speed Broadband Access) is a wholesale service that allows other broadband providers to use TM’s HSBB network to deliver broadband services without building the entire access network themselves.

TM has been a major wholesale infrastructure provider for Malaysia’s broadband industry. TM has stated that its wholesale business supports multiple local broadband providers through HSBA, with more than 670,000 ports delivered to five local broadband providers in one of its reported periods.

This is why you can have different brands selling Fibre broadband while the physical access network to your home may still be provided by TM.

For example, Maxis confirms that its agreement with TM allows it to access TM's national Fibre network, while also complementing this with Maxis' own-build Fibre infrastructure.

So the important question is not simply:

“Which ISP am I subscribing to?”

It is:

“Whose access network is actually carrying my connection?”

Shared Network Does Not Automatically Mean Slow

This is where many Fibre comparisons go wrong.

A wholesale network does not mean every customer is permanently sharing one small pipe.

Malaysia's regulated HSBB framework includes Layer 2 HSBB Network Service with QoS, where the access provider supplies connectivity between the customer's premises and a Point of Interconnection (POI), while the access seeker selects the bit rate and QoS class.

The actual performance therefore depends on how the ISP engineers the network around that wholesale connection.

A customer can have a perfectly healthy 500Mbps access connection but still experience poor performance because congestion occurs further upstream.

Think of Fibre as several sections:

Home → Access Network → Aggregation → ISP Core → Internet Exchange/Peering → International Network → Destination

Congestion at any one of these points can affect the final experience.

Why Can Some TM-Based Fibre Services Slow Down During Peak Hours?

The important word is capacity.

During peak hours — typically when many households are streaming, gaming, downloading and working online simultaneously — traffic increases dramatically.

If an ISP's available capacity at an aggregation, upstream, peering or international transit point is insufficient, customers can experience:

1. Lower speed-test results
2. Higher latency
3. Packet loss
4. Slower international downloads
5. Buffering on certain services
6. Gaming ping spikes

But this should not automatically be blamed on TM HSBA.

A TM-based ISP can invest heavily in additional upstream and international capacity and perform very well. Conversely, an ISP operating on its own Fibre network can still experience congestion if its own upstream capacity is poorly provisioned.

That is why “TM Fibre = congested” is an oversimplification.

TIME: More Control Because It Owns the Fibre Network

TIME is a different model in areas where its own Fibre infrastructure is available.

TIME explicitly states that it owns its Fibre network and operates a 100% Fibre network. It also says its network is monitored and optimised to provide consistent performance during peak hours or heavy usage.

TIME's corporate information also describes its domestic network as a fully-fibre network built around its Cross Peninsular Cable System (CPCS).

The advantage is network control.

TIME controls more of the infrastructure between the customer and its own network core instead of depending entirely on another operator's last-mile access network.

That gives TIME greater control over:

1. Network capacity
2. Access network upgrades
3. Network engineering
4. Fault management
5. Expansion
6. Traffic optimisation

However, this does not mean TIME is physically independent from every other network.

Internet traffic still eventually depends on data centres, peering networks, submarine cables and international carriers.

Allo: A Different Kind of “Owned Network”

Allo is particularly interesting because it is both an infrastructure operator and an open-access Fibre network provider.

Allo is a wholly owned subsidiary of TNB and says its network is an open-access, full-fibre infrastructure designed to serve households, SMEs, enterprises and carriers.

Allo official corporate page

Allo also describes its network as its “own Internet highway” and promotes a low-contention-ratio Fibre service.

(Source: Allo — Allo Fibre for Enterprise)

Its wholesale network is built around TNB's extensive fibre infrastructure, with Allo stating that it has access to approximately 25,000km of TNB assets across Peninsular Malaysia.

(Source: Allo — Wholesale Services)

Allo official wholesale network page

So Allo should not simply be described as “another ISP”.

It is also a network infrastructure provider that other service providers can use.

For example, Maxis previously signed an agreement with Allo to use Allo's HSBB network services, with Allo providing access infrastructure up to the customer's premises while Maxis managed the retail and service side.

That proves an important point:

Owned network and wholesale network are not mutually exclusive.

An infrastructure owner can also be a wholesale provider.

TM HSBA vs TIME vs Allo

The biggest difference is therefore not simply speed.

It is who controls the infrastructure underneath the retail broadband service.

Why Network Ownership Matters During Peak Hours

Suppose three customers buy 500Mbps plans.

Customer A uses an ISP riding on TM HSBA.

Customer B uses an ISP on TIME's network.

Customer C uses an ISP on Allo's network.

All three may see approximately 500Mbps on a good speed test.

But at 9pm, their experience can diverge.

Why?

Because the 500Mbps advertised to the customer is only the access speed.

The ISP still has to provide enough capacity beyond the access network.

A simplified example:

500Mbps home plan

→ Fibre access

→ Aggregation

→ ISP core

→ Peering / Internet Exchange

→ International transit

→ Netflix / YouTube / game server / website

If the bottleneck occurs at the ISP's international transit, changing from TM to TIME will not automatically fix it.

If the bottleneck is inside the access network, however, having greater control over that infrastructure can make a significant difference.

This is where an owned network becomes strategically valuable.

Does TIME or Allo Guarantee No Peak-Hour Congestion?

No.

This is an important distinction for consumers.

TIME explicitly markets its own network as providing consistent performance during peak hours, while Allo promotes its own Fibre infrastructure and low contention ratio. These are advantages, but they should not be interpreted as a guarantee that every customer in every location will experience identical performance.

Your actual experience can still depend on:

1. Local network capacity
2. ISP aggregation capacity
3. International bandwidth
4. Peering arrangements
5. CDN availability
6. Routing to the destination server
7. Network maintenance or faults

This is why two customers using the same ISP can sometimes report completely different experiences.

How to Tell Whether Your ISP Uses TM HSBA, TIME or Allo

This is more useful than looking at the ISP brand alone.

Some providers operate across multiple underlying networks.

Maxis, for example, explicitly lists TM-HSBA, Allo and TIME among the network providers available through its Fibre ecosystem.

(Source: Maxis — List of Providers)

CelcomDigi has also announced arrangements to use TIME's Fibre infrastructure for its Fibre offerings, particularly in condominiums and apartments.

So the same retail brand may use different underlying networks depending on your address.

That means checking the available network at your specific property can be more useful than simply asking:

“Is Maxis Fibre good?”

The better question is:

“Which Fibre network will Maxis use at my address?”

What Should You Choose?

Choose a TM HSBA-based service if:

1. TM has the strongest coverage at your address
2. You want more ISP choices
3. The ISP has good local and international capacity
4. Your area has a reliable track record
5. The price is significantly better

TM's biggest advantage remains scale and coverage.

Consider TIME if:

1. TIME's own Fibre is available at your address
2. You prioritise network control
3. You care about upload performance
4. You frequently use cloud services, gaming, video calls or large uploads

TIME's own network can be particularly attractive where its coverage is available.

Consider Allo if:

1. Allo's network is available at your address
2. You want an alternative Fibre infrastructure
3. You are comparing providers that use different underlying networks
4. Your area has good Allo coverage and competitive retail plans

Allo's open-access model also means the retail ISP and physical network provider may be different companies.

NetBijak's Take

Don't judge a Fibre plan by the ISP logo alone.

The more important question is:

Who owns the Fibre network at your address, and where does that ISP connect to the wider Internet?

TM HSBA gives Malaysia extensive wholesale Fibre access and allows multiple providers to reach customers without building an entirely separate access network.

TIME has the advantage of greater control over its own Fibre infrastructure.

Allo takes another approach by operating an open-access Fibre infrastructure based on TNB's network assets.

But network ownership alone does not determine whether your Internet will be fast at 9pm.

For consumers, the best Fibre connection is the combination of:

Good access network + sufficient ISP capacity + strong peering + good routing + reliable local infrastructure.

So when comparing broadband plans on NetBijak, don't stop at 100Mbps vs 300Mbps vs 1Gbps.

The more useful comparison is:

Retail ISP → Underlying Fibre Network → Network Capacity → Peering/Routing → Actual user experience.

That is where the real difference between Fibre providers starts to become visible.
