CISA critical infrastructure letters

[Sean Donelan <sean () donelan com>]

The CISA critical infrastructure letters are a courtesy request letter. 
If people abuse its purpose, local officials do not need to extend any 
courtesy and can deny access.

The CISA letter is only for "providing emergency communications 
sustainment and restoration support to critical communications 
infrastructure facilities."

It is NOT a general purpose, ignore anything or go anywhere letter.

Do NOT abuse the courtesy or no one will extend the courtesy.
