I filed just before lunch on the 17th using H&R Block's TaxCut. I didn't have any problems. I received confirmation last night that the IRS had received and processed my filing.

They have all sorts of other problems as well.

Yeah, I remember hearing that they had some wierd problems last year, too. I've used TaxCut for about 3 or 4 years now and really like it. I haven't had any problems. Of course, the more money you make, the more complex the filing becomes. I only wish that TaxCut was a little more helpful.
