@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
[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

Hello SmartAPI Team,
Since today (14 Jan 2026), we are facing a serious issue with the Instrument Master download endpoint.

Issue

The Instrument Master file download is hanging / stalling and not completing (download stream gets stuck). This is blocking all applications which depend on master file loading — including collector pipelines and realtime websocket token bootstrapping.

Observations

Login/authentication is successful.

Issue happens specifically during the instrument master download step.

Download does not complete and keeps waiting indefinitely (stuck mid-stream).

This was working normally on previous days; issue started today.

Impact

This is a production blocker because without instrument master:

option token mapping cannot be done,

expiry/token bootstrapping cannot be completed,

realtime subscriptions cannot start.

Request

Kindly confirm:

Is there any outage / latency issue in the Instrument Master endpoint today?

Any changes in master URL / backend caching / format?

ETA for resolution or alternate stable endpoint for master download.

Please treat this as high priority since it impacts all applications dependent on SmartAPI master file.

Thanks.
