content: Maybe. My web browser is pretty capable on its own. I know it can tell when a connection has timed out. That cloud page is intrusive and annoying, it's more like they are bragging how their service is working fine and pointing fingers to place blame elsewhere. It adds nothing.

content: Browsers are more and more "dumbing down" their messages to make them attractive to low-experience users. I agree with amyk that it is a better error report than most we see.I think most of you are completely missing the point of what CloudFlare does. When it is doing its job (making an "ordinary" website be able to handle massive hits by various methods including cacheing, etc.) you never see it and you think you are talking directly to the target website. Criticizing things we don't understand isn't a very positive indicator of intelligence and maturity.

content: Quote from: rdl on April 17, 2014, 07:59:38 pmThe connection from the browser to the San Jose site was just fine. The problem was in serving that request, hence the internal error page. More useful than just throwing an Internal Server Error / 500.

content: So let's hear reports of where CloudFlare was reporting as a location. This will demonstrate how geographically diverse the service is.Zapata says that CloudFlare was reporting from San Jose.Since I am in the Pacific Northwest of the US, I was seeing the CloudFlare server in Seattle.

content: Quote from: Richard Crowley on April 17, 2014, 11:45:53 pmThere's a list of CloudFlare POPs at their status page:http://www.cloudflare.com/system-statusQuote from: rdl on April 17, 2014, 07:59:38 pmYour web browser is not capable of generating a useful error message when it is not privy to the connection problem. The connection to CloudFlare that your browser is actually making works fine. The problem is between CloudFlare and the backend server. For this reason, only CloudFlare could (and should) be the one generating the error. The alternative would be, I don't know, sending a blank page back or something, which is just dumb.Also a cloud image has been standard for 'the internet' in networking diagrams for at least a decade. Extending that to a pictogram like this one makes perfect sense, nevermind that they've called the service CloudFlare and have a cloud for an icon...

content: Well, if it had been CloudFlare that was down you wouldn't know where it was or whether it was down. The fact that you saw the error page indicates that CloudFlare was UP, but the eevblog server itself was down. Which is exactly what the error page said. Your browser does not have that information to display even if it wanted to.

content: Quote from: wilfred on April 18, 2014, 05:03:20 amCloudFlare effecctively caches the website contents across 24 servers around the planet. No fooling around with SQL or anything else. Dave can maintain his server as it if were just a single box (which it is), and CloudFlare automatically caches the content out to a local server near you.According to the article Dave referenced, it was a server-farm wide outage of the network infrastructure. Pretty odd that the downtime was so very long. But then Dave called it a "cluster FUBAR". I strongly suspect that the inner workings of the internet is far more complex than most of us realize.

Everything virtualized and load balanced.But even if they are not too expensive, they will be more expensive than HostGator. Also setting up the servers to be scalable is not really that simple he'll need to hire someone to do it right.

content: Quote from: wilfred on April 18, 2014, 05:42:16 amBut when it comes down to it, there is always a single point of origin. Your SQL replication scheme only works if the master copy is available and participating, for example.QuoteBut the SQL replicated scheme has exactly the same vulnerability. I agree that it seems like an extraordinarily long downtime for such a major outage of both HostGator and BlueHost (which may be the same company for all we know).QuoteYes, that does seem odd. CloudFlare appears to have simply rolled over and played dead instead of serving up old content. Perhaps that is a user-configurable behavior?QuoteIts hard to find good help. But then it seemed to take an extraordinarily long time to recover. I was very surprised that a "Multi-Server Outage" took the better part of a day to fix a network hardware problem.

content: Quote from: wilfred on April 18, 2014, 05:42:16 amBecause high availability and disaster recovery come at a cost, it's a risk and financial discussion.For a website that doesn't have a critical role, it is often better economics to take the hit of an outage than to take measures for high availability or failover.
