Slower time sending from TCMS to Blox?

We've noticed lately that to send anything to Blox from TCMS, the process has severely slowed down and the story has to remain in 'Posted' workflow for at least a minute. It used to be that you could save it in 'Posted' workflow, and it was immediately on its way - and so were we.

When did this change? I have not found a release note to verify. It creates hangups - especially when saving with a breaking flag, and it gets in editors' ways when you have to physically wait to ensure the story makes it live into Blox.
