As most of you know by now, CBN has been having ongoing network issues causing periodic outages to service. We do sincerely apologize for the issues.
Last Thursday we took a manufacturer’s mandated software upgrade to our switch and router. The upgrades caused issues and subsequently reverted back however the upgrade made some as yet unknown underlying changes and thus the issues began. We brought in a switch & router expert and have now enlisted the assistance of the manufacturer’s lead software engineer to determine the issue. Early this morning we determined that the issues are most likely being caused by the way the equipment now manages hardware loops. Loops are caused by customer equipment using multiple IP addresses and broadcasting the same MAC address, thus causing the switch to send the originating traffic through out the network and ultimately back to the sender. These “Loops” cause what is know as a broadcast storm and cause the switching hardware to shut down in order to protect itself.
We are working hard to isolate and resolve the issues. We will be manning the switching equipment 24 hrs a day in order to mitigate any outage conditions this may cause until it is resolved and do again do apologize for the inconvenience we know this is causing our customers. We will update this again as soon as we can resolve the issue.
