# Why has everything stopped working?
Welcome to the wonderful world of "Preventive Justice". If you're here on a Sunday afternoon and legitimate websites have stopped loading while Twitter works perfectly, you're probably a collateral victim of the crusade against illegal football broadcasting.In Spain, judges have given a "red button" to certain sports entities. This button allows them to block IP addresses in real time without direct judicial supervision minute by minute. The problem is that they aim with a carnival shotgun, and they often shoot at shared servers where, in addition to "illegal matches", hospitals, universities, or your favorite cooking blog live.# The Theory of the Burning Building
Imagine an illegal stream is being broadcast from apartment 4B of a skyscraper. The logical solution would be to knock on the door of 4B and cut off its power, right?Well, no. The current solution is to blow up the foundations of the entire building.By blocking the IP of a service like Cloudflare, the internet provider not only takes down the pirate, but also the other 50,000 legitimate websites that shared that same digital address. If you were working or studying and your website used that IP: bad luck, collateral damage. File a complaint with the master gunsmith.# What does this diagnostic tool do exactly?
This tool performs a technical analysis in three steps to identify if your ISP is applying selective IP address blocking:Ping Google
We check if you have a pulse. If Google doesn't load, the problem is that you haven't paid your Wi-Fi bill. This is the baseline connectivity test.
Ping Cloudflare
We try to reach 1.1.1.1. It's the "canary in the coal mine" of blocking in Spain and the main target of judicial blocks.
Verdict
If Google works and Cloudflare fails, it's crystal clear: your ISP is applying selective IP blocking of Cloudflare.
# Impact of Dynamic Blocking
False Positives
Company websites, personal blogs, and government services can stop working if they share an IP with an unauthorized streaming server.
IP Filtering
Unlike DNS blocking, IP filtering prevents connection at the network level, making changing DNS insufficient to solve the problem.
Lack of Transparency
Often, the user only sees a "Timeout" error without knowing if the problem is their connection or an active ISP block.
# Questions no one wants to answer
- Is it illegal to use this? No. Pinging a server is as illegal as looking at a storefront. This tool is a passive network diagnostic. It doesn't break encryption, doesn't crack passwords, and doesn't access protected content. It just tells you why you can't access your usual websites.
- How do I fix it? If you have an active block, changing DNS no longer helps (they know all the tricks). The only real solution today is a VPN. By encrypting your traffic, your ISP can't see what you're asking for or to whom, and therefore can't block you "selectively" (or by mistake).
# Streamer Mode / OBS Widget
Are you a streamer and want to show the status of censorship in real-time on your stream? We've created a special ultra-minimalist mode, with transparent background (chroma-ready) and auto-refresh every 5 minutes.- Step 1: Add a new Browser source in OBS.
- Step 2: Use this URL:
https://jjlmoya.es/utilidades/tebas-check/stream/ - Step 3: Done! A large icon (Green/Red) will appear indicating whether your connection is clean or under judicial attack.
