[UPDATE 1 7:40PM EST]
The load balancing is in place so we should see a two times performance increase. Now that the infrastructure is in place I should be able to seemlessly add capacity as we grow.
I know it's been rough the last few weeks with all the down time but I think we're in a much better position now to handle another uptick in users.
We outgrew the previous server and have moved to a new one. This server will be a good home but requires a more complex configuration to load balance multiple instances of the nodejs process.
I am working hard to get it complete and hope to have it up this soon (tm).
