How Can a Major Bank Like Capital One Be Offline for 24 Hours?

One of the radio links in my network was down for 3 hours a few days ago. Why? An unintended interaction between parameters on the Ubiquiti radio on the client side of the link collided with a DFS radar detection event on the access point side. The access point thought it had detected radar and randomly changed to a channel the client side wasn't scanning.

As another ISP is using most of the 5GHz spectrum in the area, there are only a couple of channels that have low enough levels of interference to get decent performance out of the link. I had restricted the channels the client was scanning to reduce the recovery time from a loss of link a couple of years ago, but being groggy too early in the morning my brain took a trip to both ends to figure it out, and then more than an hour to find a channel that didn't suck.

All of this is because 10 years ago when I talked to our Local Distribution Company that owns the poles on a 2km stretch where I want to run fibre to eliminate the radio link, the design tech said they would need to replace 10 poles at a cost of nearly $100k. Sorry, I'm not paying $100k to replace 10 poles that are near the end of their useful lifespan to place $750 worth of 24 count fibre.

Complexity has unintended consequences: Lesson re-learned.

Are you asking me? I could see ti happening if the vendor was critical to the working of the system.

A power outage should take down a company, but stuff happens - you can bet the people working there are quite stressed.

If they're going to cheat consumers out of billions of dollars by lying about the interest rates on their savings accounts then they should at least provide better service so you can see your money getting pissed away without interruption, ffs.
