Hosting Health Check.

Who really hosts your website, where the server actually is, whether its IP sits on email blacklists, how your SSL and email security look, and how fast it responds from the UK — live, free, and graded. Plus Google's own PageSpeed verdict.

Checks run against public data (DNS, RDAP, blacklists, SSL) plus a live speed test from our UK network. For sites hosted elsewhere — UKBox-hosted sites already get all of this monitored for them.

What the check looks at — and why it matters

Six things your host never mentions, each one measurable.

Who actually hosts you

The company on the invoice often isn't the company running the server. We look up the network's registered operator.

Where the server really is

"UK hosting" sometimes means a UK office and a Frankfurt data centre. Every mile adds latency for your UK customers.

Email blacklists

On shared hosting you share an IP reputation. If a neighbour spams, your invoices land in junk. We check four major blacklists live.

Email security (SPF & DMARC)

Without these DNS records, anyone can send email pretending to be you — and inboxes trust you less.

SSL certificate

Issuer, expiry and validity — the padlock your visitors and Google both check.

Speed from the UK + Google's verdict

Time-to-first-byte measured live from our UK network, plus Google PageSpeed's own mobile score — the one that affects rankings.

Results are indicative, generated live from public data sources at the moment you run the check, and cached for up to 7 days. Blacklist status and speed can change hour to hour. This tool checks websites hosted elsewhere — sites on UKBox infrastructure are monitored as part of their plan.

Whatever it finds, the fix is free.

Free verified migration, our own UK data centres, first month £1 (+VAT) — and your price held for 3 years.
