I searched before posting and can see a number of members use mega.nz to host their derivatives.
I would have thought, without any brain cells left in my body, due to supporting aussie beer companies,

why not move the isos to a site that offers 50 G of free cloud or the like?

I am aware new members may be regarded as spammers and I can assure you this is a free hosting site and I have no involvement in it.
good luck
