After you file

I filed early this year 1/14/19 & was accepted on 1/15/19. I received the first red line when accepted on IRS website. I checked two weeks later & received a message saying: We can't provide any information. Called IRS they said: They are behind & they have until April 11,2019. WTH? Today is 3/10/19 still nothing. F.Y.I. I haven't got anything in the mail either.  Is anyone else having this issue?
