More details about the outage
Ericsson says that ‘network disturbances’ in a number of its customer networks occurred as the result of an issue in ‘certain nodes in the core network’. Mobile providers using two specific software versions of the SGSN–MME (Serving GPRS Support Node – Mobility Management Entity) were impacted.
Ericsson states that: “An initial root cause analysis indicates that the main issue was an expired certificate in the software versions installed with these customers. A complete and comprehensive root cause analysis is still in progress.”
