 ## Quota
 
-By default, a file `serverSide.ttl` will be installed to new PODs. Its
-current function is to set a quota for disk usage of just 25 MB, which
-is what we can be sure the current prototype can tolerate under
-load. This file is not writeable to users, but as server administrator
-you can remove it if you don't want to impose a quota. It is currently
-adviceable to remove it rather than set a large quota, because the
-current implementation will impair write performance if there is a lot
-of data.
