Hi @howardj777
Yes, we allocate extra space at the different public servers. 
For the UseGalaxy.org server, this is now automatic for everyone with an extra 1 TB of space in additional to the regular 250 GB.
For UseGalaxy.eu there is a form to make requests, and for UseGalaxy.org.au extra default space is associated with email addresses for the AU national researchers, and others can make requests with a request form.
Start here to learn how to access the extra quota space or for how to find the request forms → What should I do if my data exceeds the given 250GB of storage?
