They’re not down. That’s a you problem.

Amazon invested heavily in cloud services (AWS). They make much more profit from that than they do their utter destruction of the consume goods sector. So they don’t need to rely upon content distribution networks like the rest of the modern internet does with the notable exception of Google (whatever their garbage product is - I refuse to use google products to the point I dont even educate myself on them) and Microsoft (azure). The rest of the internet uses Cloudflare and NextCloud and a few other big named “Content Distribution Networks” or CDNs. Those are great because it lets a few big service providers set up all of the hard to maintain internet infrastructure that then is used to dynamically host webpages for much, much quicker global access and it provides a very large layer of security on top all at once.

But it does mean if they have an outage, it can affect a large swath of the internet. And it also means if your DNS is malfunctioning (which is probably the case here) then you also can’t access a ton of resources on the internet.

Clear your dns cache. Reboot your machine if necessary. If you have access, reboot your router.

Are you on a PC or phone?

Do you run a VPN or adblocker or noscript add-on?

It sounds like a DNS resolving issue, which can be from multiple issues.

If you are on a Windows PC, open the cmd.exe app and type

ipconfig /flushdns

And hit enter.
