Google Chart Published on Website stopped showing values (due to high number of requests?)

[Diogo Romão]

Hello all,

We have built a simple page in https://portugalemcasa.pt to help fight the Corona Virus in Portugal.

On this page we show 2 google sheet charts, that were published from the same google sheets file. The website has been running fine since 19h (Lisbon hour), but around 23h30 (Lisbon hour), the published graphs started to show no info (showed zero as total, and no values in the bar chart). But the graphs on the google sheets file were ok and updating accordingly, so the problem was only on the published version of the graphs.

I unpublished the graphs and republished again and the graphs came back ok. 

But since this is still scaling and lots of people are coming to the website, we are afraid it might happen again. 

Does anyone have any idea on what the problem might be? 

Might it be that the number of requests was too much and somehow it lost track and returned the graphs with no values?

It's really important for us that this issue does not repeat itself, this website is here to help fight this pandemic and we need it online more than ever.

Thanks,

Diogo
