The western economy is almost completely built using off-prem in Cloud PaaS environments. It should be pretty fun when WW3 starts and not a single hospital, school, laboratory, or factory can operate.
Which may happen as some people just got Biden to authorize (honestly I don't think he can do that by himself), without congress approval, the use of long range missiles by Ukraine.
Some people are really hard at work trying to start WWIII.
I don't think it's the russian who severed those cables.
Russia knows that if WWIII doesn't start until a few more weeks, Trump is probably going to stop the US aiding Ukraine and stop the US giving its approval for total nonsense (like allowing these long range missiles weeks before handing over the presidency).
So why would Russia severe those cable?
I think there's a very high probability the bad actors here are the same that used Biden as a puppet to give Ukraine the greenlight to fire long range missile on to Russia.
