It is fairly easy to define a reliable proxy provider, but finding one is challenging. The company should deliver consistent uptime, clean IPs, predictable performance, and transparent control. Moreover, when you buy proxy, you expect it to work smoothly on every task you use it for. What do all those features mentioned above mean, and what should one pay attention to when assessing them?
Uptime Percentage — The Foundation of Stability
Uptime reflects how often a proxy network stays online and responsive. It should be 99% and above. When the percentage drops even for a while, it creates gaps that lead to:
- failed requests;
- broken sessions;
- inconsistent data.
You want to avoid those things at all costs. It is especially harmful for activities that require continuous connectivity.
Leading providers aim for 99.9% uptime because it makes downtime nearly invisible. ProxyShard offers such uptime, as it is built on a premium, private proxy infrastructure. Its ISP and datacenter proxies are exclusive, meaning they are not shared with other users and can provide more predictable performance. This reduces bans, improves stability, and guarantees predictable behavior across all workloads.
IP Pool Size and Diversity
A large, well‑distributed IP pool is essential for avoiding blocks and maintaining high success rates. When thousands of IPs rotate cleanly across different cities, networks, and ASNs, websites struggle to detect patterns. This is especially important for tasks that involve repeated requests.
Small or poorly distributed pools create repetition, which anti‑bot systems detect quickly. Once patterns emerge, block rates rise, CAPTCHAs appear more frequently, and concurrency becomes limited. So, a reliable provider invests in expanding and refreshing its pool to ensure that customers get a high-quality rotation.
ASN Diversity
ASN diversity is often overlooked, but it is powerful for the identification of a proxy’s reliability. ASNs reveal the networks your IPs originate from. So, when too many IPs share the same ASN, platforms flag them instantly. High ASN diversity, on the contrary, mimics natural user behavior and dramatically improves success rates. Key benefits of strong ASN diversity include:
- fewer repeated fingerprints across workflows;
- higher trust on social platforms due to residential ASN mix;
- better performance on e‑commerce and SERP tasks with ISP ASN variety;
- lower risk of mass blocking on datacenter ASNs;
- more stable long‑session behavior due to balanced distribution
Providers that rely on a narrow set of ASNs expose their customers to unnecessary risk. A diverse ASN mix is a sign of a provider that invests in clean sourcing and long‑term stability.
Support Quality
Even the best proxy networks encounter occasional bans, rotation issues, or configuration challenges. When these situations occur, the pace of recovery of your workflow is determined by the quality of support. Therefore, an efficient and well-informed support team is a must. Good services have 24/7 support, clean documentation, and fast troubleshooting. Bad support is a hidden cost. Why? Delays lead to downtime, missed deadlines, and lost data.
Dashboard Features
A good dashboard gives you the data and lets you tweak settings quickly. Usage analytics, rotation controls, session management, filtering options, and billing clarity should be part of the dashboards offered. These tools are vital for enhancing performance, reducing waste, and growing confidently.
Final Thoughts
When looking to purchase a reliable proxy, take into account the features offered by the provider. The primary factors to consider are uptime, the size of the IP pool, ASN diversity, the quality of support, and dashboard features before committing to any proxy purchase. Partnering with ProxyShard can help you avoid downtime, minimize block rates, and maintain consistent long-term performance.
