speedtest is broken

it gives a 403 on the resource it tries to XHR

We had to break the app intentionally, due to hundreds of sites abusing the resource, even with cloned versions of Simple Speed. I should have added a message or disabled the whole app since then. Sorry about that.

If we can't find a resource that we can use for free, I'm afraid we can't make this app work again. It's just too expensive to pay for one. I'd be happy to change the URL, if someone can provide the URL to a 100+ MB file on a CDN.
