Does your proxy work on some sites, but does not work on others?

Did your proxy work in the past, but now it does not work?

If you answered 'Yes' to either of the above questions, then it is likely that your proxies are banned (or 'blocked') on the website you are using them on. In this article, we will talk about why this happens, as well as what you can do about it.

If you answered 'No' to both of the above questions, then please visit our article about why your proxies might not be providing connectivity to any sites. You can read about it here

Why did I get banned?

There are a number of reasons as to why a proxy can get banned, some of which are predictable and obvious, while other reasons are only theoretical guesses. Here are a few reasons:

1. You are using your proxies too fast

One of the main reasons for getting banned on a website is that you have your software configured to run too fast at a particular website. Websites will not tolerate significant, parallel, connections as it may cause harm to their services. Imagine a scenario where a website allowed a single IP address to connect to it at [1 million times] per second - wow! It's clear that they would place a ban, or block, on this IP address so that it cannot connect to their website anymore.

What is the appropriate speed that you can connect to the site you are using the proxies on? Unfortunately, that's a hard question to answer, but what we recommend is that people run their own experiments to find that rate:

  1. Set your software to run at a slow speed that will not cause a ban (ex: 1 request per hour)
  2. If you do not receive a ban at that rate, then increase it higher (ex: 2 requests per hour)
  3. Repeat this until you receive a ban, and then set your rate at the previous rate before


2. You are running at a slow rate and some of your proxies work, but others do not

The next question we frequently receive is customers asking why some of their proxies work, and why some of their proxies are banned. This is an unfortunate side effect of how IPv4 address schema works and why it impacts proxies.

There are two terms used frequently in the proxy business:

  1. Subnets (A, B, C subnets - read here for more info)
  2. ISPs (or ASNs). Example:  Verizon is an ISP;  Sprious is an ISP; etc

Why do subnets and ISPs (Internet Service Providers) matter in the terms of proxies? It's because it makes it easier for the website you are using the proxy on to see that you are sharing the same ISP or subnet as other proxy customers of ours that are also using the proxies for the same use case.

Given that the proxy industry is driven largely by certain niches (Scraping, social media marketing, and others), it's very common that many customers are using proxies for the same use case as yours. Therefore, when this happens, your proxy speeds can negatively impact each other because you share the same subnet or ISP as another customer using the same use case.

What can I do about my proxies being banned?

In this section we will cover various options you have to be more successful with your proxies with Blazing SEO:

  1. From day one, Blazing SEO made it a top priority that our customers could have the freedom to automatically replace their proxies if any of them were not working for any reason.
  2. If you run out of replacements, please contact us and our support team will assist you with restoring the replacements.
  3. Slow your proxy speed down:  As discussed in the previous section, sometimes it just requires you to slow down your rates a little in order to achieve maximum throughput.
  4. Contact us - seriously!
    1. If pricing is a problem at the rates you are running your proxies now, please contact us and we can discuss custom pricing that will make you the most profitable.
    2. There are a number of strategies we can offer you (at no additional cost) that will give your account better proxies. This includes only giving you IPs from certain ISPs/ASNs and only IPs from certain subnets that appear to work better for your use case.
      1. The reason that certain IPs on certain ISPs or subnets work better than others is that some ISPs that we partner with are on "blacklists" for certain use cases. By configuring your account to receive IPs from ISPs/subnets that work for you, you will inherently avoid getting IPs from the "blacklisted" ISPs/subnets

Did you know:  Blazing SEO has IPs spread across:

  1. 7 different ISPs/ASNs
  2. Thousands of unique C-class subnets. Just look at one of our partner's IP diversity here.
