We are aware that the 37.19.70.x subnet is facing issues with no network. This is an AT&T subnet and the routing on their side has affected the network for these IPs. We have a ticket in with them but given our experience with them it could take a day to get a response or solution. We will continue to look for updated from them. We will be posting updates here as we have them. At this point though we are just waiting on AT&T to fix the issue on their side with this prefix.
