"Sorry. The ATM is temporarily out of service." Russian media report that ATMs in the Moscow region have started shutting down due to internet issues. Cash registers are also not working, and purchases can only be made with cash.
It turns out that authorities in Moscow were forced to shut down much of the Internet due to attacks coming from Ukraine.
Both ATM's and Credit Card Terminals linked to cash registers, have to use the Internet to get transaction authorizations. No Internet equals no transaction authorization, equals cash only.
There's a lesson in this for those of us elsewhere in the world: NEVER leave home without cash money.
In our societies today, it has become common place to never have cash. The little plastic cards get used for everything out of convenience. Well, that convenience can become the worst nightmare if communications go down - or have to be taken down - due to widespread malicious activity.
Have cash money with you when you leave the house. Every time, every day.
