Queries on coin.zerodha.com

Hi Guys,

I am part of zerodha for few months. my observation is that it keeps digitalizated, updated, online good work on it.

My question here is I am investing MF on a monthly basis using SIP I was thinking of the other side of the coin say if coin.zerodha.com is down due to technical disrupt and I am in urgent need how to liquidate that fund through offline.

What are the information do I need to keep in hand regarding the MF.
