DDoS the tower? These look like they represent less than the aggregate crowd at MSG, or even a fairly dense office building (of which there are plenty in NYC). Didn't seem like enough to launch a coordinated DDoS attack. Also, just from looking at the base units, it appears the ratio of SIMs to radios/antennas is Many:1, so not all SIMs can be leveraged in a DDoS at any singular time.
