Most att techs in the bay area have been forced 6 days a week for most of the year, with over booking of there work loads. There late to about half there jobs because of the over booking of certain time slots. In some areas the ftth installs recently got moved to a different department where they are now flooded with ftth installs on top of there existing work loads. In short att is having issues keeping up with demand in the bay area.
I just had AT&T Fiber installed (sold through Sonic) at my mom's house in Santa Rosa. The first appointment was completely missed, but they did show up at 9am for the second 8-4 appointment. One of the techs told me that in Sonoma County there are only 5 techs that do installs (Sonic jobs are classified the same as commercial and governmental jobs to AT&T) and only two of them have fiber splicers. So that's what Sonic is up against trying to get these work orders actually completely.
Take it with a grain of salt since the AT&T guys sometimes exaggerate a bit.
