Spending 30 minutes strapped into a dead dark ride would really suck, though.

Do these things have battery-powered automatic emergency lights that come on in the event of a power outage?

My guess is yes, if not battery powered at least generator powered (where I work it's a natural gas generator that runs the emergency lights and outlets). There's the ever so slight possibility that a power loss could be tied to a mandatory evacuation event (like a fire).

I'm sorry, but I don't understand what any of that means :oops: :hilarious:
Its simple. Most internet providers that deliver direct lines to your business, have a ratting and promised uptime percentage.
So if the line is down and your business is affected. They have to reimburse you or in someway compensate for the lack of service.
Some lines are incredible expensive (like those multifiber node lines of 300+Mbps, that cost a few hundred of thousands per month). So paying that and getting hit by heavy outages is a big no no.

This is of course is very different from your usual consumer internet. Which doesn't promise you anything. All they have a "max" speeds(not constants), also dont promise full speeds all the time or high reliability levels.

I had thought that level was only if the customer has multiple internet connection points. I would think WDW has several.

On a major link you are going to have what's referred to as the EAST and WEST path only one is generally active at any time and ANY outage can be potentially disruptive and if the link flaps too many times it leads to a condition where in the internet routing table your path is 'dampened' i.e. removed from the tables until your route stabilizes. But generally a large organization has multiple links from multiple providers they may also have 'cheap bits' from someone like Cogent which are used for internet browsing these 'cheap bits' contracts are on a best-effort basis so unless the cheap bits goes out for longer than 1-4 hours generally there is no compensation from provider. The Five-Nines connections run a companies web presence and email because you don't want that link going buh-bye when a customer is authorizing their credit card.

I wonder what kind of protections they have!

Most ISPS usually have huge batteries based on Gel that can run at least 12 hours. But usually only work until a gas/diesel generator kicks in.
Does Universal or Disney have generators for critical components? batteries too?

Most companies shoot for only a few SECONDS of downtime per year, Unlike Disney where the website can be down for hours or days...

speaking of COGECO...
COGENT and COGECO has been buying a lot of smaller server databases lately. They recently bought my provider and not exactly happy.

I honestly believe Disney's problems are the servers and how they are programmed rather than their internet connections imho.
So they get down when their api/server interface/program..etc.. goes down.
Because the rest of the GO.com network still works just fine. (like disneyland's or disneycruiseline)

Depends on the service.
Banks do not even allow that 0.0001% rate in my point of view.
I wouldn't be surprised if they had multiple backbones to different networks AT ALL TIMES.

BGP is your friend in these cases as the organization is assigned what is known as Autonomous System Number or ASN and that link is assigned a portable IP address (not provider specific) and multiple connections are handled by several ISP's This allows for a failure of a link or an ISP without taking down service to the organization.

Does not really matter WHY Disney's web services are down, The mere fact that Disney is a media company in 2016 and ANY of it's web properties go offline for hours is simply not acceptable in todays marketplace.

One data center I worked on had 3 5 Megawatt Diesel generators, The data center could run on 2 but the third was to allow for unanticipated breakdowns and yes the data center had TWO 5 Megawatt connections to the power grid which shared NO common points of failure.

It's a requirement for certification (redundant power), among other things. Getting into a Tier IV (step lower that the top tier Datacenters) isn't that expensive. Certainly well within Disney's budgeting.

That said, there is no reason why their facing sites couldn't, or shouldn't, be on a distributed cloud. None. Even if they wanted to do it, leasing a colo of a few racks in datacenters around the country with remote hands services isn't that expensive...then run the systems on at least an A/B toggle failover or something...

I just don't get it.

DCL goes down too. I noted a 2 day outage a few months ago where the site was up, but the booking engines were down (went to Snow White or Stitch).
