Investigating
Starting 6:34 pm UTC on Monday, March 5, 2018, end-user traffic has been re-routed from CHG POP (Point Of Presence) to other optimal POPs.
There is no disruption to end-user traffic, no impact to your infrastructure, Control Panel functions, or to the integrity of the campaigns. A status update will be posted on this page when the POP is brought back into circulation.
