Emergency Linux Server Fix: Website Down, 502, Disk Full or Out of Memory screenshot 1

Your site is down and you need it back today. I log in to your Linux server, find the real cause (not just restart things), fix it, and tell you in plain words what happened and how to stop it happening again.

What's included

  • Diagnosis of Nginx/Apache errors: 502, 503, 504, 403 and SSL errors
  • Disk full (No space left on device), inode exhaustion and runaway logs
  • Out of memory and OOM killer crashes, swap and process limits
  • Crashed Node.js, PHP-FPM, Docker or database services brought back up
  • Root cause written down, with the commands I ran
  • A short list of fixes so it does not happen again

Who this is for

  • Ubuntu, Debian, AlmaLinux, Rocky or CentOS servers
  • VPS on DigitalOcean, Hetzner, Hostinger, Contabo, AWS EC2, Linode/Akamai or similar
  • WordPress, Laravel, Node.js, Next.js, Django and Docker apps

What I need from you

  • SSH access (a temporary user with sudo is best, you can delete it after)
  • The error you see, or a screenshot
  • What changed recently, if you know

How it works

  1. Message me with what you need. The first consultation is free.
  2. I confirm the scope and a fixed price before any work starts.
  3. I do the work and keep you updated in the chat.
  4. You review it, and I hand over notes, access and anything I changed.

Questions

How fast can you start?

Message me with the error and I start as soon as I see it. Most outages are fixed within a few hours of getting access.

What if the fix needs more than an hour or two?

I tell you what I found and the price for the bigger fix before I do it. You never pay for work you did not agree to.

Is it safe to give you SSH access?

Create a separate user for me, and remove it when we are done. I work only on what the job needs and list every change I make.

What you'll get

  • Production-ready implementation tailored to your goals
  • Clean, maintainable code following modern best practices
  • Deployment to secure infrastructure with monitoring
  • Handover with documentation and full access

Tech stack & tooling

  • Ubuntu and Debian servers
  • Nginx, SSL and firewalls
  • Security hardening and updates

How we'll work together

We start with a short requirements discussion, agree on scope and milestones, then move through implementation, review and handover. You get clear visibility into progress and a stable deployment at the end.

What kind of projects do you take on?

SaaS products, business web apps, dashboards and APIs, plus DevOps and Linux work: deployments, CI/CD, server setup and maintenance. I take on new builds as well as existing codebases.

How much does a project cost?

It depends on scope. Fixed-scope packages with starting prices are listed on the Services page. For custom work I send a fixed quote after a free discovery call, so you know the price before any work starts.

How long does a typical project take?

Small fixes and deployments usually take days; a full web app or MVP takes weeks. Every proposal includes a timeline with milestones, so you know what ships when.

How do payments work?

We agree on scope and price first, and no advance is needed to start the conversation. Fixed-scope services can be paid securely online by card. Larger projects are split into milestones agreed up front.

Can you work on my existing codebase or servers?

Yes. I regularly fix bugs, improve performance, add features and migrate infrastructure on existing projects. We usually start with a short review so the estimate is based on the real code.

Do you work with clients outside Bangladesh?

Yes. I work remotely with clients worldwide, schedule calls around your time zone and reply to messages within 24 hours.

What happens after launch?

You get a handover with documentation and full access to your code, servers and accounts. Ongoing maintenance and support are available if you want someone to keep things running.
