The data center hosting our server that this and several other of our websites run on will be replacing a piece of network gear on August 7th
They will have to power off the servers for the 2 hour duration from 1 AM to 3 AM Eastern time - most of us east coasters will likely never notice, but some folks in California, Hawaii, Australia, etc may see the website down - Just know that it is a planned maintenance period and not an outage issue.
