Does anyone know if this halt is related to the recent switch over to the new Linux based platform? (http://news.ycombinator.com/item?id=686116)

it is a new platform, hard to tell but I wouldnt go so far as to say linux is to blame, its more likely to be exchange software, they've gone from native to fix 5, so its using a new protocol, new os, new software stack and most likely new hardware stack

I wonder if it's HFT related? A group of rogue algorithms gone exponential? There are certainly people worried about that...

Unfortunately sometimes fail over isn't a solution. Until they've at least narrowed down the problem, a fail over system may make things worse.

Personally, I'm curious about the testing that was done - given the complaints and problems that have been reported so far, did they even try to run the new and old systems simultaneously for any period of time to verify that the various components could all keep up properly? Or at the very least, did they try to test the system at full load for a decent period of time?

I don't think famoreira was trying to blame Linux. --That's just the part of the new system that you can reference easily.
