TV Guide flooded with 'To be announced' for a few days now

For a few days now our TV guide has been flooded with 'To be announced' in place of the scheduled program names.

Some channels show up to the next six hours or so of program names but after that it's either all TBA or almost all TBA with a few program names interspersed.

ALL my scheduled recordings on the DVR now either show TBA or have been deleted.
