There is a networking issue at the old datacentre. For devices routing through the old location, this is causing a slow down in event traffic.
There was a compromise of some of our old servers and a DDOS - one of the reasons we moved to the cloud to eliminate the impact of such events. A lot of out traffic still routes through that location though, which affected users, the routing of traffic though this location will reduce as we steadily update the configuration in devices.
