instrument list API extremely unreliable and not robust

Rithvik

@admin instrument_master_url='https://margincalculator.angelbroking.com/OpenAPI_File/files/OpenAPIScripMaster.json'
isn't loading again, it generally takes 30sec to load now from past 5 min i am getting no response

code used:
resp = requests.get(url=instrument_master_url)

after 10min i tried again, now it took 90sec to execute,
the perfomance of this api is not reliable, it works but not consistently and reliably
please look into to it![alt text](image url)
[sometimes it works , sometimes it takes 30sec(best so far), sometimes it takes lot of min and sometimes it doesn't work at all blocking the execution of code and other dependent parts
