If visitors inside mainland China are part of your business, where you host stops being a commodity decision. The same site that loads in under two seconds in Frankfurt can take eight seconds — or fail outright — from Shanghai. This page explains the three real options, what each costs you in speed and paperwork, and how to decide without committing to a rebuild first.
Why hosting abroad is slow from China
Three separate things stack up, and only the first is about distance:
- Congested international links. Traffic between China and the rest of the world passes through a limited number of gateways. Latency is high and, at peak hours, packet loss is real. This affects every request, including the ones your page makes to load fonts, scripts and images.
- Blocked third-party assets. Google Fonts, Google Maps, reCAPTCHA, YouTube embeds and several popular CDNs are unreachable from inside mainland China. A browser doesn’t fail these instantly — it waits. One blocked font stylesheet in the
<head>can hold up rendering for seconds even though the rest of your site is fine. In our experience this single issue causes more “the site is broken in China” reports than hosting location does. - TLS and DNS round trips. Every extra handshake is amplified by the latency above, which is why sites with many third-party domains degrade much worse than their raw page weight suggests.
Practical consequence: moving hosting closer without also fixing blocked assets often produces a disappointing improvement, and teams wrongly conclude that hosting wasn’t the problem.
The three options
1. Mainland China hosting (ICP filing required)
Best possible performance for domestic visitors, and the friendliest option for Baidu, which favours domestically hosted sites. The cost is regulatory, not technical:
- An ICP filing (备案) is mandatory for any site served from mainland servers.
- The filing is issued against a registered Chinese business entity. No entity, no mainland hosting — this is the constraint that decides the question for most foreign companies.
- It takes weeks, varies by province, and cannot be accelerated by paying more.
- Your domain must be one the registry accepts for filing, and the site must be reachable and compliant during review.
2. Hong Kong (no ICP filing)
The pragmatic middle ground and where most foreign companies should start. No filing, no Chinese entity, live immediately. Performance is clearly better than US or European hosting for mainland visitors, though still behind mainland hosting because traffic still crosses the border. For a brochure site, a B2B catalogue or a lead-generation site, this is usually good enough — and you can migrate to mainland later once filing is done.
3. Keep hosting abroad, fix everything else
Sometimes correct, and the cheapest test. If your China traffic is modest and your site is mostly static, replacing blocked assets, self-hosting fonts, removing unnecessary third-party scripts and putting a CDN with Asian points of presence in front can recover much of the gap. We’ve told clients to do exactly this instead of taking their money for a migration.
How to decide
- Do you have a Chinese business entity? No → mainland hosting is off the table for now; choose between options 2 and 3.
- Is Baidu part of the plan? Yes → mainland hosting matters more, because Baidu treats domestic hosting favourably and crawls it more readily.
- How much does China traffic matter? A distributor-facing brochure site has different requirements from a store taking orders.
- Measure before you migrate. Test your current site from inside China first. Knowing whether your problem is latency or blocked assets changes the answer entirely — and it’s a free thing to check.
What to check before any migration
- Inventory every external domain the site loads. Anything on
googleapis.com,gstatic.com,google.comoryoutube.comwill not resolve for mainland visitors. - Confirm your DNS provider answers reliably from within China; some do not.
- Plan the redirect map if the domain or URL structure changes, so you don’t lose existing rankings.
- Decide where email will live. Moving web hosting without planning MX records is a classic way to silently lose inbound mail.
Common questions
Can I host in China without a Chinese company?
Not on the mainland — the ICP filing requires a registered domestic entity. Hong Kong hosting requires no filing and is the standard answer for companies without one.
Does an ICP filing apply to Hong Kong servers?
No. Hong Kong sits outside the mainland filing regime, which is precisely why it’s the common starting point.
Will moving to Hong Kong fix everything?
It fixes distance, not blocked assets. If your pages still request Google Fonts or reCAPTCHA, mainland visitors will still see them hang. Both need handling.
Do I need a Chinese domain (.cn)?
No. A .com works and can be filed, provided the registrar supports the process. Domain choice is usually a branding decision rather than a technical requirement.
How long does an ICP filing take?
Commonly several weeks. It depends on your province and on whether your documents are complete and consistent. Treat it as a scheduling constraint on launch date, not a task that can be compressed.
