Ping to the Google DNS IPs of 8.8.8.8 and 8.8.4.4 may be restricted for some customer devices. Accessing the Google DNS service itself is unaffected.
A DataSIM customer has been misusing these IPs for ICMP/PING/ECHO services and this has caused Google to temporarily apply a Denial Of Service (DoS)/Flood attack protection block on their devices. No other customers appear to be affected.
To avoid this issue devices must be set to the DataSIM ICMP servers of 172.30.255.88 and 172.30.255.44 for keep alive PING's and other types of device originated automated network tests.
It is also recommended to allow the device to use the automatically allocated DataSIM DNS service instead of a third party service external to the network.
Please contact support if devices are repeat rebooting or demonstrating other unusual behavior.
We will continue to monitor this, typically the service will resume within a matter of hours.
