Test my connection!

Want to know whether the site is down, or if it's just you?

What is this about?

Despite common belief, computers are not connected to the internet by magic, but with technology instead. If you want to visit a website, your computer needs to connect to the right server. This happens over either IPv4 or IPv6, which are different versions of the Internet Protocol, a way for computers to talk to each other over the internet.

Originally every computer used IPv4, but the internet expanded, and IPv4 has run out of room to grow. That is why, in 1995, IPv6 was developed with enough room to grow. However, many internet service providers and network administrators do not use IPv6. A consequence of this is that if you lack either IPv4 or IPv6, there will be websites you cannot access. And at the moment you will get exactly the same error message you see as when you type in a wrong URL or click a broken link. (Meaning you may very well have encountered this problem without realizing.)

This website helps a bit with knowing whether you are having issues regarding this. There are 2 "your internet" boxes to your left that each show whether you are connected to the internet. One is for the old IPv4 and one is for the new IPv6. Ideally they both say you are connected, but there is a good chance one of them says "No connection!". A lot of websites will break if you don't have an IPv4 connection. When lacking IPv6, there will be a few broken websites, but this number is growing. If IPv6 is missing, we would encourage you to ask your ISP or network administrator to implement it.

Here above you can paste or type a link to test if that website is online. You can also see if the website uses IPv4 and/or IPv6, and it will inform you if your lack of connection would prevent you from visiting the webpage. Please note that there are a few exceptions where the tool misreports a site as offline when it's not. This is due to strong security mechanisms on those websites blocking our service.

To the right is a list of other tools that check if a website is online or not. Not every tool handles IPv6 correctly, so I made a list of them and noted down what it can or cannot do properly.

Here's what the columns mean:
👁️ Will the tool properly detect modern (IPv6) websites?
⚠️ Is there a warning when the checked website won't be available to you?
📶 Is the downchecker itself available over modern networks?
