Space-X needs to get Starship and the v3 Starlink satellites into orbit. There is now a shortage of Starlink service and waitlists for purchase of the residential units and they can't deploy the v2 sats fast enough. The v3 sats will have 10x the capability/coverage as the v2.
I guess between overselling the service, deployments to disaster areas and the popularity (5 million current subscribers), they are running out of bandwidth.
