Hong Kong and Singapore are the two default choices for audiences in Greater China, Taiwan, Hong Kong, and Southeast Asia. Compare real latency ranges, bandwidth cost, and network quality.
There is no universally better choice between Hong Kong and Singapore — only what fits your users. The test is simple: where are they? If your audience spans regions, the answer is often not either/or but a combination.
Core rule: Greater China, Taiwan and Hong Kong → Hong Kong. Southeast Asia (Indonesia, Vietnam, Thailand, Malaysia) → Singapore. Both → run both and split traffic by geolocation.
Short answer: choose by audience, not by reputation
| Your users are mainly in | Pick | Why |
|---|---|---|
| Mainland China / Taiwan / HK | Hong Kong | Shortest cross-border path |
| Southeast Asia | Singapore | Direct peering into the regional backbone |
| Japan / South Korea | Tokyo / Seoul | Closest deployment |
| US West Coast | US West | Shortest trans-Pacific path |
| Mixed globally | Both HK and SG | Geolocation-based traffic splitting |
How large is the latency gap?
Typical RTT ranges from southern China. Real numbers vary by carrier and time of day.
| Origin | Hong Kong | Singapore |
|---|---|---|
| Guangdong / Guangxi | ~10–25ms | ~45–70ms |
| Shanghai / Hangzhou | ~25–45ms | ~55–85ms |
| Beijing | ~35–55ms | ~65–95ms |
| Taiwan | ~10–30ms | ~45–65ms |
| Southeast Asia (Bangkok / Jakarta) | ~40–70ms | ~20–45ms |
Notice how the last row inverts: for Southeast Asian users, Singapore is faster than Hong Kong. That is exactly why "Hong Kong is closest to China" is not a complete rule.
Always measure it yourself. These are reference ranges; carrier differences can reach 2×. See the self-verification section below.
Bandwidth cost
Hong Kong datacentre space, power and cross-border capacity are more expensive, so the same bandwidth usually costs slightly more than in Singapore. Cheaper is not always better though:
How to do the math: multiply the unit price gap by your bandwidth for the monthly delta, then estimate the conversion lift from lower latency. If a 7–10% conversion improvement covers the delta, Hong Kong pays for itself.
- Small bandwidth (under 5 Mbps) → the price gap is marginal; prioritise latency
- Large bandwidth (50 Mbps+) → use a CDN and convert bandwidth cost into traffic cost
- Heavy traffic → per-traffic billing plus a CDN is typically 50%+ cheaper than fixed bandwidth
Network quality: peak hour is the truth
Latency measured at midday flatters everyone. What users actually feel is the 8–11pm cross-border peak:
- Packet loss: good lines stay under 1%; weaker ones hit 3–5% at peak
- Jitter: unstable latency makes real-time apps (voice, live calls) audibly choppy
- Bandwidth guarantees: shared capacity gets squeezed at peak — "dedicated" or "committed" bandwidth is more reliable
For real-time workloads, buy dedicated or BGP multi-line capacity, and ask for peak-hour loss figures before you sign. Static assets and VOD are better handed to a CDN, which takes the cross-border hop off the critical path.
Compliance and content strategy
- Hong Kong requires no ICP filing — bind your domain and go live
- Singapore also requires no filing and is friendlier to Western users
- If you primarily serve users in mainland China long-term, evaluate filing requirements
- For cross-border data flows, check the destination jurisdiction data-protection rules
Hybrid: one site across two regions
When your audience genuinely spans regions, running both is usually the right call:
- Deploy the same application in Hong Kong and Singapore
- Use intelligent DNS to split by user location
- Keep the database in one region and reach it from the other over a private link or read replica
- Put static assets behind a CDN to further cut cross-border requests
This roughly doubles infrastructure cost but minimises latency for everyone. For revenue-sensitive businesses it usually pays back within months. Traffic between the two regions should travel over a private backbone rather than the public internet — see Cloud Enterprise Network.
How to verify it yourself
Skip other people's benchmarks and test it directly:
- Launch a minimal instance in each candidate region
- Run
pingandtraceroutefrom your real user network for 24 hours - Record average latency, jitter and loss specifically during peak hours
- Then measure real page loads with
curl -w "time_connect:%{time_connect} time_total:%{time_total}\n"
Test for a week before deciding. A wrong region costs you continuously; testing costs a few dollars.
