Hope cip-99 can extend from 3 hours to 6 hours

Recently we upgraded serveral Nodes, found it may take 1~4 hours to catch up the latest state(Aliyun cloud server located in HK).

If our server stopped unexpectedly, we may take 10 miniutes to receive the alert, 30 minutes to work status, 3 hours sync to latest state, 3 hours 40 minutes in total.

Hope can extend to 6 hours, otherwise we have to prepare a backup server to handle it.

The node restart time has been decreased to less than one hour
