Per J. Keating on fedora-announce-list, Fedora 10 will be further delayed. The new release date is now set at 25 November.
This wasn’t unexpected given the infrastructure problem of the past few weeks. The infrastructure problem created huge impact on development of Fedora 9, bringing work to a halt for at least a month, as shown in the lack of updates (security and regular) since the update servers returned to service. This announcement shows the infrastructure problem is having a major impact on Fedora 10 as well. To what extent only time will tell.
