Narrative:
This form does not address tmu (traffic management unit) issues; but tbfm (time based flow metering) was impacted by a decision to adjust tbfm bandwidth which impacted tbfm operations. Aircraft were being metered to hou and aircraft were being scheduled to dfw when tbfm stopped working because of a stale data feed. I do not know if this information is correct; but I was told that the harris company adjusted the bandwidth. The surrounding centers were also impacted. Why would a decision be made to adjust bandwidth without communication with natca; FAA; air traffic; tmu; etc? Who made that decision and what communication needs to happen before this is to occur.
