I finished the 100th floor on the Summit, went back to the lobby, and then tried to fast travel to DC but got Delta-01 error during the loading screen.
Loaded back into my character and tried to fast travel and got error again. Took the elevator to the 1st floor, tried again and got error (video below).
I even tried answering a backup call but same thing there. I then matchmade and joined someone else's Summit, cleared a room, then left the group, tried again, and still error.
I also tried after closing the game and launching it again and then turning off the console and starting the game again.

Tried logging onto my 2nd character who's WT5 and in the DC and got the error there too.

Before I went to the Summit I did a mission and a control point in the DC and didn't have any problems there.

I would recommend following the connectivity troubleshooting steps to ensure you have the best possible connection, this may prevent you from experiencing the Delta error again.
