Answer 1

store localy analytics.js, but it is not recommended by google: https://support.google.com/analytics/answer/1032389?hl=en

it is not recommended cause google can update script when they want, so just do a script that download analytics javascript each week and you will not have trouble !

By the way this solution prevent adblock from blocking google analytics scripts
