Hi Anssi and Christopher, I happened to just see this email now as I was catching up on emails to this mailing list. We (Hostopia Australia) are responsible for mirror.digitalpacific.com.au. Long story short, mirror.crucial.com.au was consolidated into mirror.digitalpacific.com.au a while ago as a part of Digital Pacific's acquisition of Crucial. This one would be my fault as I had taken care of this particular consolidation. The use of a CNAME was purely to avoid potential issues from users who had hard-coded repos into their servers (I am sure you can understand this). I can only really say that notifications to mailing lists was one of the last things on my mind during the time of consolidation (there was a lot going on), although feel free to remove mirror.crucial.com.au from the list. Apologies if this had inconvenienced anyone. Last thing is, the contact for mirror.digitalpacific.com.au should be networking at digitalpacific.com.au Feel free to reach out to me directly should you have any questions. Thanks! Regards, Matthew.
