- throw0101a 6y agoAre you referring to CenturyLink’s 37-hour, nationwide outage? > In this instance, the malformed packets [Ethernet frames?] included fragments of valid network management packets that are typically generated. Each malformed packet shared four attributes that contributed to the outage: 1) a broadcast destination address, meaning that the packet was directed to be sent to all connected devices; 2) a valid header and valid checksum; 3) no expiration time, meaning that the packet would not be dropped for being created too long ago; and 4) a size larger than 64 bytes. * https://arstechnica.com/information-technology/2019/08/centurylinks-37-hour-outage-blocked-911-service-for-17-million-people/ https://arstechnica.com/information-technology/2019/08/centu...
