This is crazy. I stopped for gas just now having no idea what was happening. It’s out. People here told me they’d been to other stations and found the same. pic.twitter.com/7LDVdUXPo4
“Have you ever worked on safety certified software?”
I am the chair of a DO-178C committee for safety critical software for airborne systems. I think that counts.
For you to claim not having backups is a “single point of failure” tells me you don’t understand the term.
On a proper enterprise failover system, the moment the first system realizes it’s screwed or even acting strange, the load and connections get seamlessly or nigh seamlessly shifted to the next, identical system running off the same data from just before the corruption. If that one goes down, it goes to the next machine down the line, etc. They’re not even all running off the same file store, and if need be as part of the architecture involves file system snapshots every (say) 15 minutes, mirrored across multiple machines.
It’s expensive but it’s the current standard for enterprise critical apps.
“Finally, who’s the idiot who thought making critical infrastructure accessible via Internet was a good idea?”
You need to get out of that Neanderthal mindset, EVERYTHING is now on the Internet. It’s absolutely wonderful...what could go wrong? LOL.
I’m sure if we all drove Electric Cars this wouldn’t be a problem.
Too bad this isn’t the Year 2035 after all the Green New Deal mandates have taken hold.
Back to reality. This is occurring with only ONE Pipeline being disrupted? We are screwed six ways to Sunday.
“It’s being reported that they move 100M/gal a day.....”
Nothing to sneeze at, they said 2.5M Barrels per day, so yes, 100M gallons per day, although I’ve even see 3.0M Barrels.
Colonial Pipeline’s owners are
Koch Industries (a.k.a. Koch Capital Investments Company LLC, 28.09% stake ownership)
South Korea’s National Pension Service and Kohlberg Kravis Roberts (a.k.a. Keats Pipeline Investors LP, 23.44% stake ownership)
Caisse de dépôt et placement du Québec (16.55% stake ownership via CDPQ Colonial Partners LP)
Royal Dutch Shell (a.k.a. Shell Pipeline Company LP, 16.12% stake ownership)
Industry Funds Management (a.k.a. IFM (US) Colonial Pipeline 2 LLC, 15.80% stake ownership)
Yeah, though that’s still an issue for a lot of SMB implementations.
I understand the term perfectly thank you.
Where’s the redundancy?
I get how it works...
That’s fine for enterprise apps - not for things ‘safety critical’....which is, imo, more relevant for this application.
Pipelines Matter
See my post 242. They aren’t discrete backups so much any more with enterprise failover systems.
Or put another way, if one of your failover systems goes down and it’s not a hardware issue, you can quickly rebuild it from the rest of the machines and resources in the net then put it back in the ‘rotation’.
One could argue that a failover system would be even better for something safety critical because it continues running without significant data loss and only a slight initial delay. Restoring from traditional backup means the system is down while you restore.
Don’t ever use monster and dodge and diesel in the same sentence again please.
*laughs in real truck*
Tell him real men use an Allison transmission.
Most safety critical systems are also ‘real time’ applications - any delay is deadly. You couldn’t use any of these techniques, the software wouldn’t be certifiable.
“Virtually nothing is air-gapped in our infrastructure... zilch, nada, nothing.”
We could probably learn a bunch from the Iranians. Israel is able to defeat them, but it is NOT easy and the Iranians know exactly how to air gap.
“”Pipelines Matter””
Very good!!!
You may want to slightly alter it to BPM = Buried Pipelines Matter.
“You knew that and I knew that. How many others reading this thread also knew that? Generally speaking, I consider the overwhelming majority of those who read this forum pretty smart and independent thinkers. Still, I wonder how many really knew this?”
I didn’t, but I FULLY understand Complacency and Normalcy Bias, along with management not seeing a problem until it slams them in the face, so no surprise at all for this FReeper.
“She has an education degree...”
For what it’s worth, she does have a BS in math.
*** Reminds me of the mantra of the parents of teenagers: When their story doesn’t make sense, it means they’re lying.***
I remember my kids lying. They embellished till the lies were as plain as the nose on their face(s).
Kinda like the current administration and the MSM. They all really do think we’re as dumb as a box of rocks. It’s easy to see that they’re full of lies.
We have a WINNER! Give that man a cigar.
