Looks like they've been down for about 14.5 hours currently: http://reports.panopta.com/cloudharmony/server/57551

MaxCDN and HDDN are offering discounts to existing customers looking to migrate. http://admin.simplecdn.com

I've had them do the same to me, it seems that if you come close to making use of your allocated resources, they'll come up with any excuse to terminate your contract.

They being SimpleCDN, not its (ex-)providers?

Looks like they shouldn't have outsourced their entire infrastructure.
