I wasn't necessary thinking of just within the UK. I am primary concerned with our own network connection . We have a 34Mbs connection to JANET, but that is shared with other resources and not dedicated to EGEE. I wonder if this is a bottleneck for users of our tier 2 site, and if so, what bandwith we should be aiming at. Dave brian davies wrote: > I do not know what a generic connection speed between sites.
