Hosting customers don't leave

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.

A majority are faithful — but it's not universal

Across 646,271 owners of two or more live business domains, 73.8% keep all of them with a single provider, and the average owner concentrates 89% of their domains with their primary one. That still leaves a measurable minority — 26.2% — who deliberately multi-home, and 2.8% 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.

The surprise: borders barely matter

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 the 327,732 owners whose domains span more than one country-code, 71.9% still keep every one of them with a single provider — set that beside the 73.8% across all multi-domain owners and the whole effect of crossing a border is the gap between those two numbers. Cross-border complexity, which should fragment the relationship, barely does. The provider that wins a multinational's first domain tends to keep the rest, wherever they operate.

Faithfulness is a book-quality signal — and it varies

Measured per provider, the share of a provider's multi-domain customers who use it exclusively ranges from 74.0% at the top down to 42.8% for a pure cloud/DNS layer. Those are the ten books charted below — the eight largest hosting books and the two largest CDN/DNS layers, one denominator for every figure in this paragraph. Across them, no hosting book falls below 56.5%, while the layers top out at 50.9% — so across these ten, the hosting books all sit above the layers. 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.

The ten largest books we track, as archetypes rather than named providers (named scores are a product-tier feature), ordered by exclusivity. 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.

And it's conscious — customers are loyal to the brand, not accidentally to the owner

A fair challenge: consolidators own many brands, so a customer with domains at two sibling brands would count as "loyal" to the group without knowing it. Measured: that case is nearly empty. Of group-loyal owners, 98.6% keep everything within a single brand — the loyalty is a relationship the customer actually chose, not an artifact of hidden ownership. The flip side is a finding for the consolidators themselves: cross-brand wallet expansion inside a group is close to nonexistent — the remaining 1.4% is every loyal owner who spans two brands of one group. Multi-brand portfolios run as silos, and the second domain goes to the brand the customer already knows.
