Cloudflare Migration in Sheffield
Moving Sheffield organisations onto Cloudflare, where proxying changes what your origin can see. Requests now arrive from Cloudflare rather than from visitors, so anything relying on the client address — logging, rate limiting, geographic rules, fraud checks — sees one of a handful of addresses until the origin is configured to read the real one.
Why this comes up
The problem
Every request now appears to come from the same few addresses, and rate limiting blocks everybody at once.
What you get
What we deliver
- Origin configured to read the real visitor address from the forwarded header
- Rate limiting, logging and geographic logic verified against the corrected address
- DNS records audited during the move, since proxying is decided per record
- Records that must not be proxied identified, such as mail and certain services
- Caching rules set deliberately rather than left at defaults for dynamic content
- Origin locked down so it only accepts traffic through Cloudflare

Cloudflare Migration in Sheffield — common questions
- Why does the visitor address change?
- Because Cloudflare terminates the connection and makes its own to your origin. The real address travels in a header instead, so any application logic reading the connection address gets Cloudflare's — which breaks silently rather than producing an error.
- What breaks first?
- Rate limiting and abuse controls, usually. They see all traffic as coming from a small number of addresses, so a limit intended per visitor triggers against everybody simultaneously — and it is not always obvious that this is what has happened.
- Should every record be proxied?
- No. Mail records must not be, and some services behave badly behind a proxy, so the migration involves deciding per record rather than enabling it everywhere — mail delivery failing after a DNS move is a common and avoidable outcome.
- Does the origin need locking down?
- It should be. If the origin address remains reachable directly, anyone who finds it can bypass everything Cloudflare provides, so restricting the origin to accept only Cloudflare traffic is what makes the protection meaningful rather than optional.
- Do you work with businesses across South Yorkshire?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Yorkshire & the Humber, including Sheffield and the surrounding South Yorkshire area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Sheffield businesses do you usually work with?
- Manufacturers here typically want to replace long-standing spreadsheet processes with something reliable, without disrupting production while it happens. Beyond that we work across Advanced Manufacturing, Metals & Materials, Healthcare, Higher Education and Digital.
- Do you cover the areas around Sheffield?
- Yes — we work throughout Yorkshire & the Humber, including Leeds, Nottingham, Manchester. Sheffield is an urban area of roughly 730,000+, and we take on work across the wider South Yorkshire region rather than the city boundary alone.
