AT&T Outage
Earlier this morning, I was having issues with my AT&T phones (IE: no service). Downdetector was showing some issues in the Northeast as well.
Here is the output of one of my testing phones during the hours of 9AM EST to approximately 10:30AM
Notice the quality/RSRQ is constantly at -20 and level/RSRP is at -132
Here is a new source that has confirmed the issue as well.
