All,

Something bigger than just CONDUIT users occurred on the 19th. We had
numerous users of other servers complain of similar drops in transfer
rates. A few of them were also able to move downloads to a new location
where speeds were normal. We believe that this issue was outside of NCEP
due to that reasoning. Having said that though, is anyone still seeing
abnormal rates?
