I’m Madalin, the developer behind HTTP 5xx Help. If you’ve ever stared at a “500 Internal Server Error,” “502 Bad Gateway,” or “504 Gateway Timeout” while customers refresh and revenue ticks away, this site is for you.
HTTP 5xx Help is a new home for two things:
- Practical, no-nonsense guides on diagnosing and fixing website and web application failures.
- Hands-on services to get your site stable, fast, and secure—and keep it that way.
What “HTTP 5xx” means—and why it matters
HTTP 5xx errors indicate something went wrong on the server side. Unlike 4xx errors (often user or client issues), 5xx errors are on us—the infrastructure, the app, or the integration points. They’re noisy, frustrating, and often avoidable with the right visibility and practices. My goal is to help small businesses, startups, and solo founders resolve incidents quickly, understand what caused them, and reduce the chance they happen again.
Who I work with
- Small businesses and local services running a website or online booking system
- SaaS and e-commerce owners who can’t afford downtime
- Agencies needing a reliable backend and ops partner
- Developers who want an extra set of eyes on infra, performance, or security
Services offered
Whether you need a quick fix or a deep dive, I tailor the engagement to your stack and constraints.
Incident response and recovery
- Rapid triage of 5xx errors (500, 502, 503, 504), application crashes, and outages
- Log and metrics analysis (journalctl, systemd, Nginx/Apache, PHP-FPM, Node, Python, Go)
- Rollback/blue-green strategies, hotfixes, and stabilization plans
Root cause analysis and prevention
- RCA write-ups in plain English with technical detail for your team
- Resilience improvements (timeouts, retries, circuit breakers, health checks)
- Runbooks and checklists for future incidents
Performance and scalability
- Profiling and tuning for PHP, JavaScript/Node.js, Python, and Go services
- Database optimization (indexes, slow queries, connection pooling)
- Caching, CDN integration, and queueing for stability under load
Infrastructure and operations
- Linux server configuration and hardening
- Web server and proxy tuning (Nginx, Apache), TLS, HTTP/2/3
- Containers and orchestration (Docker, Kubernetes, Incus), CI/CD pipelines
- Monitoring and observability setup (Prometheus/Grafana, ELK/EFK, OpenTelemetry)
- Backups, disaster recovery, and cost-conscious cloud strategies
Security and network hygiene
- Security baselines for small teams (least privilege, secrets management, SSH hygiene)
- WAF/CDN configuration (rate limiting, bot rules, DDoS protections)
- Dependency and vulnerability scanning, patching workflows
- Practical guidance to reduce risk without slowing your team down
Web development support
- Bug fixes, refactoring, and maintainability improvements
- API reliability (timeouts, rate limits, validation, idempotency)
- Migrations (shared hosting to VPS/cloud, monolith to containers) without vendor lock-in
Simple ways to work together
- Quick Fix: Targeted help to resolve a specific error or outage and stabilize.
- Deep Dive: Comprehensive audit of your app and infra with a prioritized action plan.
- Ongoing Care: Proactive monitoring, updates, and monthly improvements.
You’ll get clear estimates, transparent communication, and documentation you can keep—no black boxes.
