There is now a fourth file server available to download from located in Washington DC, USA. This brings the overall network connectivity for the Nexus sites up to some 3.2 Gbits. Having trouble downloading from the other file servers? Try the Washington one and spread out the load a bit.
The Seattle and Dallas file servers will be taken off-line at separate times in the course of next week, for 24 hours at a time, while the hard-drive space is upgraded to accommodate the increasing number of files served by the Nexus sites. I'll keep you updated in the site news when this happens.
