linode clould is not working from pass two days?

There haven't been any outages reported in Mumbai according to the status page so I don't think this is related to an issue with the data center. Can you be more specific about what you're experiencing? What you're trying to do that isn't working or what errors you are seeing?

You may also want to open a ticket and let the Support Team know exactly what instances you're having an issue with, since they will be able to see specific information relating to your account.
