If your website or email is unreliable, I'll get it stable - quickly and safely. ✅ I fix hosting faults, DNS problems, and business email delivery/authentication for SMEs and agencies. I'm based in Edinburgh (UK) with 18+ years in hosting and infrastructure. I work carefully on live systems: evidence-led changes, low risk, properly tested. 🖥️ Hosting & server issues When hosting is unstable, it shows up as downtime, slow performance, timeouts, or strange intermittent behaviour. I track down the root cause, fix it with minimal disruption, and leave the setup cleaner and easier to maintain. Typical work includes: • cPanel/WHM faults • VPS/server issues • service outages • mail service problems • performance bottlenecks Common scenarios: site slow or timing out, cPanel/WHM behaving oddly after updates, mail services failing intermittently, or a migration left things half-finished. 🌐 DNS & domains DNS is where small mistakes turn into big symptoms - especially during migrations or "quick" edits. I make sure the domain points to the right place consistently, on the right nameservers, with no conflicting records. I usually help with: • Cloudflare / registrar DNS • record clean-ups • migrations / cutovers • A / AAAA / CNAME / MX / TXT fixes • split DNS issues Common scenarios: site/email broke after a DNS change, validation records won't verify, or different tools show different answers. ✉️ Business email & deliverability Email issues are almost always traceable if you follow the evidence: headers, bounces, routing and authentication records. I fix delivery and authentication so mail flow is predictable and spoofing is harder. The usual fixes are: • SPF fixes • DKIM setup/repair • DMARC setup/repair • routing / MX issues • forwarding breakage • provider checks (M365 / Google / cPanel) Common scenarios: mail landing in spam, "SPF/DKIM fail" bounces, forwarding breaking authentication, or a provider move that wasn't finished properly. 🔎 How I work (no drama, no guessing) I don't "try a few things and see what happens". I start with evidence, make small changes, and test properly before moving on - so you don't swap one problem for three new ones. My process looks like: • evidence first • small changes • safe rollbacks • proper testing • clear notes 🧾 ✅ What you get You'll get a clear diagnosis, a safe fix plan, and confirmation the issue is resolved (or a clear reason if a third party is blocking something). What I deliver on every job is: • what's broken (and where) • why it's broken • what changed • what was tested • what to watch next 🧰 Tools / platforms I work across the common stacks used by SMEs and agencies. That typically includes: • Linux • cPanel/WHM • Plesk • Cloudflare • Microsoft 365 • Google Workspace 🎓 Certifications cPanel University: cPSP • cPP • cPA • CWSA-1 • CWSA-2 🚀 To start quickly I'll tell you exactly what I need once I've seen the problem. If you want to cut the back-and-forth, here's what helps: If it's DNS: • domain + where DNS is hosted • what changed (and when) • the record(s) you're unsure about If it's email delivery/auth: • sending platform/provider • one header or bounce example • your domain (to check SPF/DKIM/DMARC) If it's hosting instability: • hosting type (cPanel/VPS/etc.) • what's happening + when it started • any errors/log snippets you already have
