What time of day is this happening?? if its around lets say .. when you get home from work... it is congestion. If ithas been your phone and wireless on your phone it could be a fiber cut that happened last week. Or trunks could be overflowing.. it could be a number of things. everday i am putting out fires like this
either a cell tower down, trunks over flowing calls on prime time business hours, congestion on hi speed internet because they begin to to pump out more speeds on dslam blocks without adding new T3s to compensate.
there are number of reasons for this. Also they could be retiring old equipment or adding new equipment and sometimes you will have short time outages all this should ideally be done during maintenance window but sometimes they do it during the day.
