Google Adword developers have just announced that users will be unable to access their Google Adword accounts between the hours of 1PM and 11PM on Saturday, September 22nd.  While ads will still run properly during the period, users will not be able to view their account information or change their ads.  Google Ads developer Kevin Winter states that the changes are "necessary to keep adwords and DFP running smoothly."  To learn more about Google Adwords Downtime, visit this link.
