I’m sure that this isn’t a problem at my end.
The page works fine for me here in Bangladesh, on Firefox.
I did find one of the URLs provided by @elcste to be detected as malware…
I’m still being taken to a scammy page seconds after the page loading. I’m currently using Samsung Internet on my Galaxy S9. However, when I go to the homepage of the Pi Flavour Maker website (which appears to not be affected) and then click About, it takes me to the correct page with no problems. However, if I go directly to the About page using 4G, it doesn’t redirect me anywhere.
