•fcMRI (seed, matrix, ICD) is stable across 8 sites in a Traveling Subjects dataset.
•No major site, scanner manufacturer, or day-of-scan effects were found (GLM).
•No outlier sites were found (leave-one-site-out analysis of variance).
•Reliability substantially improves when averaging data over multiple days.
•Data can be combined across sites to increase power without impacting reliability.
