Production scraping problems are rarely caused by bugs.
They’re caused by architecture.

A scraper can pass tests, return stable responses, and run without errors — while the usefulness of the collected data steadily declines under real load.

In this video, we look at why scraping systems break down in production environments and why treating them as simple scripts leads to hidden data loss.

We discuss:
- how modern websites turn scraping into a distributed system problem;
- why scaling traffic reveals design assumptions that don’t hold;
- how anti-bot mechanisms affect response quality, not just availability;
- why successful requests can still produce unusable data;
- and why post-ingestion monitoring misses the real failure points.

In 2026, proxy servers are part of core business infrastructure.

In this article we explain why companies rely on proxies not just for anonymity, but for traffic control, automation, and secure access to online platforms at scale.

Key use cases covered:
- protecting corporate data and DevOps workflows
- managing traffic and access in large organizations
- web scraping, SEO, and data analytics automation
- stable access to advertising and marketing platforms
- supporting distributed teams and global operations

The guide shows how proxy servers evolved into a strategic layer for modern IT, marketing, and analytics teams.

Managing multiple cloud phones without proper proxy control doesn’t scale.

In this video, we show how to set up proxies in DuoPlus and run multiple cloud phone sessions — each with its own proxy and region.

What you’ll see in practice:
- how to add proxies manually and in bulk;
- supported proxy formats and validation via IP checker;
- how to assign proxies to existing cloud phones;
- how different proxies and GEOs affect cloud phone behavior.

We also demonstrate how several cloud phones run simultaneously with different proxy configurations — and why centralized proxy management is critical for mobile account operations at scale.

It’s about controlled setup, validation, and scalability — where results depend on your proxy infrastructure.

A proxy connection error is rarely random — it’s usually a signal that something in the setup or network path is misaligned.

In this article, we break down the most common reasons behind the “Unable to connect to the proxy server” error and show how to diagnose it systematically, without guesswork.

What’s covered in the guide:
- why proxy connections fail: configuration errors, network restrictions, or server downtime;
- how firewall rules and antivirus software can silently block proxy traffic;
- practical steps to verify proxy settings and test connectivity;
- when switching IPs is the correct solution — and when it’s not;
- how to prevent recurring connection errors with proper monitoring and maintenance.

The article focuses on real operational scenarios — from web scraping to marketing workflows — where proxy stability directly affects productivity, anonymity, and data access.

Dashboards look healthy. Pipelines keep running.
But the data still can’t be used — and teams often notice this too late.

In this video, we explain why failed and “successful but useless” requests silently drain value from data stacks — and why the real problem isn’t analytics or models, but data validity at the point of collection.

What we break down:
- why HTTP 200 doesn’t mean usable data;
- how incomplete, late, or inaccurate responses slip through pipelines;
- why most quality issues are discovered *after* ingestion;
- the hidden economic cost of invalid requests;
- why **valid responses** are becoming the new enterprise currency.

This isn’t a technical edge case.

It’s a structural blind spot in modern data infrastructure.
