About NHS outages
NHS sits at number 80 on the worldwide traffic ranking with about 55.8M organic visits a month, and the address it resolves to belongs to Microsoft Corporation. NHS answers on a single published address.
The authoritative name servers are ns1.nhs.uk and ns3.nhs.uk, with the registration held through Nominet UK. Nhs.uk sends an HSTS header, so browsers refuse it over plain HTTP. The certificate nhs.uk presented to us was issued by DigiCert Inc, with 107 days left on it at first check, and negotiated over TLSv1.2. Our first check of nhs.uk returned HTTP 200 in 662 ms, of which 79 ms was name resolution and 71 ms the connection. The request to nhs.uk passed through 1 redirect before it settled on https://www.nhs.uk/. Those figures are the baseline this page measures nhs.uk against from now on, every 20 minutes.
What to do if NHS is not working for you
Is it them or you?
Our last check reached nhs.uk normally, from a different network, resolver and route than yours. If it is broken for you, the fault is most likely local or too narrow for a single probe to see. Our next automated check runs within 20 minutes and this page updates with it.
The first thing worth trying
Try a search-engine cached copy. Reference content changes slowly, so a cached version is usually just as good for what you needed.
How reference services typically fail
Pages load from cache while anything dynamic - search, editing, the API - fails. Because so much of these sites is cacheable, partial availability is the normal presentation. The rest of the steps, and why this category breaks the way it does, are on our reference status page, with more background in how we record outage history.
The link below unfurls into a live card showing the verdict, so whoever you send it to sees the evidence rather than your word for it.

Free, no account, and it will keep working. We ask nothing in return beyond the link back.
NHS measured against its peers
How it compares with other reference services
Over the last 30 days NHS ranks 3 of 4 reference services we monitor, measured on recorded uptime. The category averages 100.0%, and NHS sits at 100.0%. The steadiest in this group is NAMU.
On speed, NHS answers our checks in about 380 ms against a category average of 236 ms - Slower than its peers. Response time is not availability, but a service drifting well above its own normal is often the first sign of trouble.
What the last 24 checks looked like
Across the most recent 24 checks, the quickest response was 307 ms and the slowest 591 ms, against a 30-day average of 380 ms. The chart above plots each one, so a widening spread is visible before it becomes an outage.
All figures are our own measurements, taken every 20 minutes from one network. What that can and cannot see is set out in the methodology, and every reference service is listed on the category page.

An expired certificate stops browsers loading a site entirely while the server itself stays perfectly healthy, which is why we track it beside the uptime figure.
.NHS status: Common questions
Is NHS down right now?
NHS is up and responding normally. This page is refreshed by an automated check that runs every 20 minutes from an independent network, and by reports from visitors.
Why can I not reach NHS when you say it is up?
Because an outage can be partial. Our check runs from one network and asks for one page. Your problem may be regional, may affect only the mobile app, or may be local to your connection, DNS resolver or browser cache.
How reliable is NHS?
NHS has been reachable for 100.0% of the last 2 days we have measured, with 0 seconds of recorded downtime.
Does NHS have an official status page?
NHS does not publish a public status page, which is why independent monitoring and user reports are the only external signal available during an incident.
NHS discussion
Useful comments say what broke, roughly where you are and roughly when it started - That is what turns a pile of complaints into something other people can act on. Links are shown as plain text and carry no SEO value, so there is nothing here worth spamming.
