They are HUGELY bandwidth constrained right now, according to the forums. I believe they may be moving to another area of campus and MIGHT be able to get a little extra bandwidth (that was what I last read at least). What I do to help the download situation is set boinc to be able to download 16 wu's at once. Sure, most of them timeout / retry etc... before they download, but it still speeds up the whole process overall. I got lucky once and had WU's (the 8MB astropulse WU's) having the same download issues as you are having. But then they had their weekly maintenance, and RIGHT when their upload/download servers came back online I must have hit retry, cause i downloaded like 10 WU's at 1MB/s each. Tried again like 20 minutes later and it was back to "normal"
