how to query more than once every 2-3min to overpass.api?

I have an application with leaflet and overpass.api written in javascript. I use overpass-layer plugin to query to OSM data. My problem , when i query 2 times to overpass.api i get an Too Many request error.

http://overpass-api.de/api/status status shows me that there is a limitation. There is 1 available slot, and after i send a request my IP is blocked for a time period (30sec-3min). Why is my IP banned already after 1 query? And why for so long?.

in wiki there stands http://overpass-api.de/api/ :

"Both servers have a total capacity of about 1.000.000 requests per day. You can safely assume that you don't disturb other users when you do less than 10.000 queries per day or download less than 5 GB data per day."

Need to query more than just once in 3 min. How can i achieve that?

this is an example query i sent with my application.

I just created the biggest query possible with my application slot is available after 5min when i use this query:

area[name="Berlin"]->.a;

(node(area.a)["landuse"="industrial"]["name"];
way(area.a)["landuse"="industrial"]["name"];
relation(area.a)["landuse"="industrial"]["name"];

node(area.a)["landuse"="industrial"]["phone"];
way(area.a)["landuse"="industrial"]["phone"];
relation(area.a)["landuse"="industrial"]["phone"];

node(area.a)["landuse"="industrial"]["contact:phone"];
way(area.a)["landuse"="industrial"]["contact:phone"];
relation(area.a)["landuse"="industrial"]["contact:phone"];

node(area.a)["landuse"="industrial"]["website"];
way(area.a)["landuse"="industrial"]["website"];
relation(area.a)["landuse"="industrial"]["website"];

node(area.a)["building"="industrial"]["name"];
way(area.a)["building"="industrial"]["name"];
relation(area.a)["building"="industrial"]["name"];

node(area.a)["building"="industrial"]["phone"];
way(area.a)["building"="industrial"]["phone"];
relation(area.a)["building"="industrial"]["phone"];

node(area.a)["building"="industrial"]["contact:phone"];
way(area.a)["building"="industrial"]["contact:phone"];
relation(area.a)["building"="industrial"]["contact:phone"];

node(area.a)["building"="industrial"]["website"];
way(area.a)["building"="industrial"]["website"];
relation(area.a)["building"="industrial"]["website"];
);
out body;
>;
out skel qt;

It gives me all tags with name, phone,contact:phone,website for landuse=industrial and building=industrial
