Restricting incoming calls to landlines in Tokyo Will the amount of traffic increase due to vaccine reservations?

NTT East has restricted the number of incoming calls to landlines in Tokyo from 9:00 am on the 6th due to the increase in telephone traffic.

This is a measure to prioritize emergency calls such as calling the fire department and police, but due to this effect, it is difficult to make a connection when making a call to a landline phone in Tokyo.

It seems that the amount of communication is increasing because the local governments in Tokyo are accepting reservations for vaccination against the new coronavirus via landlines.
