The reason that all of these websites went offline is because

a US Cloud computing services provider, known as Fastly, had a technical glitch.

So, what is Fastly? Well, Fastly is a content delivery network or a content distribution network. This isn't the first time that a CDN has gone down in the way that it did today.

You know, this has happened multiple times over the years.

Cloudflare is a company you may have heard of.

They had a big problem last year and in 2019 as well. Amazon has also had its own issues with its Amazon Web Services company.

And some people are now saying that, you know, there are big, big parts of the Internet in the hands of an increasingly small number of companies and maybe this needs to change.
