We don't really know how much people care, because we know very little about the situation, only that a genset they refer to as "older" failed in some catastrophic manner and caused the outage. I've never shopped around for hosting of this sort but I would expect that prices vary widely and that to some extent, you get what you pay for in terms of reliability. There could be redundant sites, or at the very least, redundant gensets located in separate buildings, or newer/higher quality gensets, or any number of other things There is a lot of web hosting, this forum included, which I would not call mission critical. Nobody dies if it goes down for a few days and very few people are even particularly inconvenienced, is it worth paying more for higher reliability? Only Dave can answer that since it's his money, but given the rarity of outages I would vote no. I mean this is ONE outage, and it's impossible to measure reliability from a single failure. Maybe it was an accident waiting to happen and it is miraculous that things held on this long, or maybe it's all top notch high quality gear that is meticulously maintained and something still blew up because, sometimes no matter how careful you are shit happens, we don't know. I'm going to guess that the truth is somewhere in the middle.

Also after looking at the photos and Google maps, an observation:

Don’t go with a facility with no crash wall, no fence and parks a trailer probably with a nice propane bottle actually in the boundary of the building. If they do that then there’s probably 9000 even worse things inside the building you can’t see which are waiting to take your business out.

The trailer wouldn't bother me particularly, it looks in good shape and those things don't often just go up unless someone is using one as a meth kitchen. Of all the details observable in the photos, restaurant in the building is the most eyebrow raising. It's not that rare for a restaurant to catch fire although even that doesn't happen every day.

Sure but a year or two back Dave changed hosts to this crowd due to server unreliability and in 8 years I've be aboard this one by far was the largest outage.
We may have been inconvenienced some however Dave will have taken a financial hit due to his shop being down and loss of forum advertising.
Dave's very lucky gnif does most of his admin on the cheap.

At least they didn't invoke force majeure and weasel out entirely!

Yes, or of actual messenger pigeons!

With that said, the critical downside of the station wagon or pigeon is the latency! :P

I'm sorry I'm dragging this so far off-topic; I promise to sit on the Naughty Step for a while and Think About What I've Done. But meanwhile, have a ponder about the effective latency in even, say, a thousand parallel, error-free, get-the-label-speed 10Gbps direct links for that amount of data. How many miles apart do your data centres have to be before it's quicker to send the data via wires than wheels?

And don't get me started on the effective data rate of a cargo plane worth of 6GB/mm3...

OK, I've arrived at the Naughty Step. Sitting in 3... 2... 1...

Well, that’s not really what latency means... ;) (Latency is the minimum time for a single bit to go in one end of the “pipe” and come out the other end. As a metric, it isn’t dependent on the total size of the data you’re sending.)
