What's going on with USPS processing in NOLA?

I've never had a problem with USPS mail, but things have gotten odd lately. Since January 1st, I've had 2 different packages hit major delays once they hit the USPS processing center in New Orleans. One was misdirected twice, first to St. Rose, and then to the wrong Slidell post office (adding an entire week). The second package arrived at the New Orleans, and the sat for 4 days before finally heading out.

And yesterday, I received a large manilla envelope in Slidell postmarked in New Orleans on January 6th. 11 days for a piece of first class mail to go from New Orleans to Slidell is ridiculous.

Does anyone know what is going on?
