The Hub update error

I am getting a ton of "Update failed: cURL error 28: Operation timed out after 55001 milliseconds with 0 bytes received" errors, across numerous domains, when trying to update from The Hub. Is there a better way to run all updates? The Hub has so far proven to be unreliable at best. It will not update a theme that we use on hundreds of sites. Most of the time I have to refresh The Hub pages because it freezes while updating.
