Narrative:
Takeoff was southbound on runway 17R at dfw on the soldo RNAV departure. A left turn direct to soldo waypoint was given then as filed. The next 2 waypoints dropped out and we flew direct to sqs (sidon). Uim and eld did not come up on the FMS. Just north and west of uim; ATC called and asked us to go direct to uim. A few minutes later we were asked to give ATC a call. At our destination; I called dfw ATC and he informed me that we were the fourth carrier to do this very same thing today. All airlines have been affected by this. There were no conflicts or loss of separation.
