There is a general shutdown of all US government services due to non agreement on spending bill within the deadline. Check the news
This means that many services will have reduced staff. There is no need to worry though as far as data on NCBI is concerned, as it will stay up as long as it needs minimal staff for running. And this situation is a temporary one, as there are other more important departments affected due to this general shutdown. So the senate has to come for a solution sooner or later to break this logjam.
And I have one more question: how much disk space do I need to make a copy of all the information contained in the ncbi (mirror)?
Start talking to Google, probably they might rent some data-warehouse for this :)
NCBI ii HUGEEEEEEEE !!!
