lightning is a reimplementation of a part of visa, caching for response time and still recording on a blockchain, no? reminds me of https://en.wikipedia.org/wiki/Greenspun%27s_tenth_rule
No, that is not how lightning works.

In this case, based on other commenters, there does seem to be something of a real outage (obviously not for the whole US though). However, as someone who has worked this style of job, I can describe why these fake outages happen: While 95% of people are understanding about this, some small portion of customers are unable to separate the store they're shopping at from the minimum wage employee they're talking to. If…
Yeah that’s great point. That’s probably a very likely reason. It’s a good way to preempt any customers possibly getting angry at the employees or the business. Defer the blame to a tier above your control. I wonder if there is a term for that? I could see the same phenomenon happening other scenarios.

If I pay for something, and the merchant doesn't deliver - I have a legal right to a refund which the credit card provider will give me. This is standard in the UK. If I'm daft enough to pay for something with Bitcoin - well, transactions are irreversible by design. So in the case of non-delivery, or a broken / misdecsribed product, there's no mechanism to force a refund. If your credit card provider treats you like…
You have no right. Visa decides who wins the dispute. That may be the standard but get someone having a bad day and you might get the non-standard treatment.
Nor my experience.
Why does this get to the front-page of HN is the real question..
Many people don’t understand how card networks work. Generally there are many parties involved in a payment. There is an issuer (usually a bank), acquirer bank, the visa network itself, the payment processor company, etc. If peering between any of these entities is interrupted, there are sometimes “stand in authorization” that allows the card to continue to work, or people may assume the visa network itself is at fau…
Yes, there is even a movie about it. imdb dot com/title/tt1251757/
We were not informed of any outages that required tech org employees to come online. (Perhaps another region handled it, but usually it is communicated company wide)
I suspect that a dependency client (Acquirer, Issuer Processor) had issues which caused the network to be down.

>For example, Tom Thumb, Albertson's, and Kroger's are all the same company. This is not true.
Ah, yeah, I apparently missed with Kroger there. Market Street, Randall's, Von's, United, Safeway, Tom Thumb, and Albertson's are apparently the same company. See: https://www.albertsonscompanies.com/home/default.aspx
There are many third party vendors that depend on this business to provide entry points for merchants to the VISA network.

Ha! Great to know there is a word for this phenomenon. I encountered this first hand on the Wikipedia page “Substances Poisonous to Dogs” [1] subsection about Onions & Garlic. The only citation eventually self-references the same Wikipedia page from whence you started. I was already skeptical that the single most common vegetable and ingredient in human food was somehow poisonous to dogs, but now convinced it’s entir…
American kennel club claims garlic is poisonous to dogs, if they eat several cloves per kg body weight... That's a lot of garlic.
