As many of us with some knowledge of website programming have suspected, the problems with the enrollment website have little to do with being "oversubscribed." Rather, the problem is in the very design of the site. According to this article:
Five outside technology experts interviewed by Reuters, however, say they believe flaws in system architecture, not traffic alone, contributed to the problems.
For instance, when a user tries to create an account on HealthCare.gov, which serves insurance exchanges in 36 states, it prompts the computer to load an unusually large amount of files and software, overwhelming the browser, experts said.
If they are right, then just bringing more servers online, as officials say they are doing, will not fix the site.
"Adding capacity sounds great until you realize that if you didn't design it right that won't help," said Bill Curtis, chief scientist at CAST, a software quality analysis firm, and director of the Consortium for IT Software Quality. "The architecture of the software may limit how much you can add on to it. I suspect they'll have to reconfigure a lot of it."
One possible cause of the problems is that hitting "apply" on HealthCare.gov causes 92 separate files, plug-ins and other mammoth swarms of data to stream between the user's computer and the servers powering the government website, said Matthew Hancock, an independent expert in website design. He was able to track the files being requested through a feature in the Firefox browser.
It is not clear why the upload function was included.
"They set up the website in such a way that too many requests to the server arrived at the same time," Hancock said.
He said because so much traffic was going back and forth between the users' computers and the server hosting the government website, it was as if the system was attacking itself.
Hancock described the situation as similar to what happens when hackers conduct a distributed denial of service, or DDOS, attack on a website: they get large numbers of computers to simultaneously request information from the server that runs a website, overwhelming it and causing it to crash or otherwise stumble. "The site basically DDOS'd itself," he said.
Obamacare does nothing at all to increase the number of doctors and nurses; it does nothing to lower the cost of health insurance; and the basic sign-up site does not work, so God knows what the rest of the IT will be like. In other words, this monstrously awful legislation was written by people who don't know anything about health care, don't know anything about health insurance, and don't know anything about health care IT!
But, in keeping with the folks in charge, while they are blindingly ignorant, they don't even know...that they don't even know.
