Non-random thought: It wasn't a cyber-attack.
?? Theory ??
Why do I say that? --Because it's the excuse that the press is reporting.
Pipelines have manual overrides for safety just like all modern industry and power systems. They aren't just hooked up to the net. I'm willing to bet this pipeline predates the internet as well, so 30ish years at least.
From what I've seen from a few other sites, the pipeline was leaking about a million gallons of gas and was forced to shutdown 2 weeks ago for repairs. Gas suppliers and truckers say there was plenty of gas available. Then the media stirred a panic just like the Toilet Paper scare of 2020 and people did what they do, they panicked. Funny how Russia "hacked" the US again...it's never China.
