I believe Syniverse only comes into play when you text someone on a different carrier than your own. Syniverse is basically the middle-man for that message delivery, and a server of theirs just spooled ~150k messages until someone rebooted/fixed that server.

It sounds like these messages were never originally delivered to begin with, so "re-sent" is not exactly accurate.

It seems there is a company that has everyone's text messages..

"Some mobile carriers rely on a third-party text platform called Syniverse to relay messages. The vendor said in a statement that its IT staff unknowingly caused the texts to be delivered this week."

Yeah, like who (in the private sector -- we all knew the NSA already
are doing this) has access to and is archiving *everyone*s text
messages? And why?
