Delay in Nifty Index Ticks, but Options Data is Fine - Data Provider Issue?

I'm encountering a strange issue where I'm seeing a significant delay (30+ seconds) specifically in the Nifty index tick data from WebSocket feed. During these periods, the tick data for all my other subscribed option symbols continues to arrive perfectly in real-time without any delay.

My monitoring system caught the issue and generated the following alert, which shows that no new Nifty tick had been received for over 30 seconds, while everything else was working.

2025-07-11 12:47:01.201 (#Log Time): 
ALERT - NO TICK DATA RECEIVED ORDER MANAGEMENT {'tradable': False, 'mode': 'full', 'instrument_token': 256265, 'last_price': 25182.45, 'ohlc': {'high': 25322.45, 'low': 25136.75, 'open': 25255.5, 'close': 25355.25}, 
'exchange_timestamp': datetime.datetime(2025, 7, 11, 12, 46, 31),  # time from provider
'received_timestamp': datetime.datetime(2025, 7, 11, 12, 46, 32, 230084)} # time when code received data

Since the delay is isolated only to the Nifty index instrument and not affecting my other option symbol subscriptions, I suspect the issue might be originating from the data provider's end.

Has anyone else experienced similar selective delays specifically for an index while other instruments are fine?

Thanks for any insights!
