Zak asked:

> If I open the oeis.org page for some  query
and then keep it open while doing some (lengthy) calculations -
is the server busy or not?

The answer is No. Our server sends you the html file once,
and that's the end of it.

Even if we had a silly blinking sign that said "Send money to the OEIS"
"Send money to the OEIS" ...
that would be running on YOUR computer, not on our server.

Best regards
