ALERT: THE COLLECTION IS OFFLINE BECAUSE OF 100x HIGHER DOWNLOADS THAN NORMAL. The website is up but the matrix files are not accessible. THE PROBLEM IS EXCESSIVE DOWNLOADS FROM JOBS RUNNING ON AWS ITSELF, POUNDING THE DATA. We have no estimate on when this will be resolved, but it will take some time (weeks perhaps?). Please do not contact us to ask when it will be up; the answer will be the same as this alert box. If you are running these AWS workloads, please revise them. All interfaces we provide (Python, MATLAB, Java gui) download a matrix ONCE and then cache it locally. Do the same or use these interfaces.
