It took about 90 seconds to load the 3 pictures on the main page. Are they using a Raspberry Pi for a server?

It's really getting silly buggers with the download speed.
----------------------------------------This is particularly apparent with the Africa Rainfall Project. Downloading a 15MB file at about 12KBps is a joke in my book.

Perhaps if as many people as possible implement automatic scripts to retry pending transfers every minute (not project update, specifically "retry pending transfers" ) the network admins might be able to find the bottleneck instead of just ignoring it and hoping it will go away on it's own.

One thing which would reduce the bandwidth requirement for me (and I suspect for many others) would be flagging files used by a high proportion of tasks for a project as persistent to avoid them from being deleted when the last task has been completed and having to be re-downloaded the next time tasks are allocated for the project.
----------------------------------------The specific example which jumps to mind is the 102MB mcm1.dataset-sarc1.txt file for MCM1.
