What nginx ????

'Welcome to nginx on EPEL!'
When visit bitcoiwatch and bitcoinchart... WTF ?

NGINX is a fast lightweight replacement for Apache web server.  I've been getting similar errors on Mt Gox for 3 days.  I suspect this is the recent DDOS attacks causing this.  Mt Gox, if you read this forum USE CLOUDFLARE FFS!

Cloudflare is better than Prolexic?

I have not used Prolexic so I can not provide a comparative analysis.  All I can say is Spamhaus just had the largest DDOS attack in the history of the internet and survived with CloudFlare.  Based on what I'm seeing so far this DDOS on Mt Gox is no where near that scale.

I have no idea how Prolexic does DDOS mitigation.  What I do know is CloudFlare uses anycast to spread your site all over the world.  You would have to DDOS a whole lot of locations in order to affect a site.  Maybe someone familiar with Prolexic's methodologies can chime in.

You can't cache a trading engine like you can a static website.

They don't even cache the homepage or any part of the site at all it seems.  The engine part is a database which is not being DDOS directly.  It is the front end that is DDOS'd and the main site is not reachable.  I do not have experience in handling financial sites so, I'm sure the architecture is much more complex than sites I currently deal with.  However I suspect major stock exchanges have developed technologies to deal with these type of issues.

At any rate they should at the very least cache the homepage and things that can be so other parts of the site can be accessed.  If the engine is only accessed internally I would think the front ends could be cached.  The problem as I know is the latency and again that is not something I deal with on this scale so I wont speculate the details.
