Reports I am hearing is that it was a software issue. There was a software update that went into place and the switch didn’t like it. They pulled back the update to mitigate the issue. When they did the system lost necessary compatibility coding. Kicked a lot of mobile numbers out of system.
Read that as well. Easy for the mind to run rampant on the conspiracy theories, but easier to remember humans are running these systems…. Human error is the MOST likely culprit…..
