Roller Network has long used Sprint PCS phones for voice and EVDO data services, but for the first time there was a complete outage of all Sprint CDMA towers citywide. According to our logs Sprint EVDO failed at 14:23:24 local time. We restored some devices by forcing them to "roaming only" mode (although roaming was quite congested only 1xRTT) by 17:40, and the Sprint CDMA towers were back online sometime after 18:30. We turned off roaming only mode the next morning.
Roller Network uses EVDO and SNPP for out-of-band paging in the event that all fiber and/or copper based facilities are lost.
