The EU’s cyber security agency European Union Agency for Network and Information Security announced on Tuesday it has released the results of its Annual Incident Reports 2012, which among other things showed that there were 79 major telecom outages in 2012.
Fifty percent of outages hit mobile telephony/mobile Internet, with around 1.8 million users per incident.
This figure remains consistent with the high penetration rate of mobile telephony and mobile Internet in the EU.
In the report, ENISA said the 79 outages occurred in 18 countries, with nine countries reporting no major outages.
Meanwhile, those incidents caused by overload and resulted in power failures saw the greatest impact in regards to the number of affected users.
For 75 percent of incident reports, as well as fixed and mobile telephony, and fixed and mobile internet services, the root cause was “System failures”.
Hardware failures were found to be the most popular cause of “Systems failures”, while software bugs was second most popular.
Switches were found to be the most frequent point of failure, followed by mobile network home location registers.
Root cause third party failure incidents, mostly power supply failures, impacted approximately 2.8 million user connections per incident on average.
Incidents involving overload affected around 9.4 million user connections per incident on average.
Incidents caused by natural phenomena, such as storms and heavy snowfall, lasted the longest, on average around 36 hours.
In January 2011, ENISA released a report on governmental cloud computing targeted at senior managers of public bodies who have to make a security and resilience decision about migrating to the cloud, if at all.
