Every hosting provider can measure its own churn. None of them can measure faithfulness — because the question lives outside any one provider's book. When a business owns several domains, does it keep them all in one place, or spread them across providers and countries? Only someone who can see the owner across every provider can answer that. We can.
Across ~177,000 owners of two or more live domains, 53% keep all of them with a single provider, and the average owner concentrates ~81% of their domains with their primary one. That leaves a large, measurable minority — nearly half — who deliberately multi-home, and a stubborn ~6% who spread across three or more providers. For a provider, that minority is the entire upsell-and-defend map: the customers already half-somewhere-else.
Churn tells you who left. Faithfulness tells you who was never fully yours to begin with.
You would expect a business operating across several countries — a national domain here, a regional one there, a .com — to pick a local provider in each market. It mostly doesn't. Among owners whose domains span multiple country-code domains, 51% still use one provider for all of them — essentially the same as single-market owners. Cross-border complexity, which should fragment the relationship, barely dents it. The provider that wins a multinational's first domain tends to keep the rest, wherever they operate.
Measured per provider, the share of a provider's multi-domain customers who use it exclusively ranges roughly two-fold. The large European consolidators command exclusivity from roughly half to nearly two-thirds of their multi-domain customers; budget-tier and pure-registrar providers sit lower, their customers routinely keeping a foot in another camp. That is book quality, orthogonal to book size: a smaller book of exclusive customers is stickier, more upsell-ready and more defensible than a larger book of always-shopping ones — exactly the distinction an acquirer or lender wants and cannot get from a raw domain count.
Archetypes, not named providers (named scores are a product-tier feature). Faded bars are CDN/managed-DNS providers — a layer run alongside a host, where low exclusivity is expected, not weakness.
One honest read of the same data: CDN and managed-DNS providers show low exclusivity, and that is correct — they are a layer run alongside a real host, not instead of one. We flag them, because reading their low score as churn risk would be a mistake.
Every figure here is queryable through the HostingBrain connector. The aggregate loyalty distribution is
on the free tier via the customer_faithfulness tool; per-provider exclusivity scores are analyst
tier. In Claude or any MCP-compatible assistant, this is the whole brief in one prompt:
“Using HostingBrain, tell me how faithful hosting customers are: what share of owners with multiple domains keep them all with one provider, the average share they hold with their primary provider, and whether it changes for customers operating across multiple countries. Then rank providers by how many of their multi-domain customers use them exclusively, and flag which are CDN/DNS layers where low exclusivity is expected.”
Resolves to customer_faithfulness (distribution, free) and its per-provider leaderboard
(analyst). Ask definitions('faithfulness') for the bias control and folding.
Ask who's really loyal — and who's already shopping. HostingBrain answers inside Claude and any MCP-compatible assistant, with the denominator and caveats attached to every number.
