Wondering as many I am sure do, why does the US Social Security website at https://secure.ssa.gov/ or socialsecurity.gov shutdown basically overnight? Is it because of legacy systems running batch processing overnight? Is a security issue? Is it staffing? Is it overnight maintenance? Why would a critical US Government website used by millions of people daily be shutdown at a time when many in the US are trying to get access?  Remembering that the web never sleeps. Why would a website need to shutdown daily and be offline preventing access to important personal and financial details related to benefits.
