Mirrors not allowing adding of core or core32 sources and slow. Dont know if this is normal note here.
Upgrade really slow, removed mirrors, used MCC to add in again, very very slow, core main and core32 main refused to DL.
I'm sure that mirrors are being updated constatntly as we approach RC and final, so its probably nominal, but a note can't hurt if its not an expected outage.
Ta again for all the work.
