I'm surprised that Google Sheets hasn't been throttled on that url yet.
At one point I provided live tracking data to a popular event site using Google Sheets and advised their web team to create a local cache of the data and refresh it every 10 minutes. Instead they ignored that advice and included the document itself into the home-page. The document was hugged to death within about 30 minutes of going live on a four day event and it took days for Google to increase their throttle, at which point it didn't matter any more, since the event was over.
I realise that Google has infrastructure to handle this load, but an international event, with a (then) Google Apps account, was unable to make enough noise at Google to fix things in a timely manner.
