Keletas įdomesnių faktų:

  • Most incidents affected mobile telephony or mobile internet (about 50%).
  • Incidents affecting mobile telephony or mobile internet also affected most users (around 1,8 million users per incident). This is consistent with the high penetration rate of mobile telephony and mobile internet in the EU.
  • Incidents caused by overload followed by power failures respectively had most impact in terms of number of users affected times duration.
  • For most incident reports, as well as for the four services, (fixed and mobile telephony, and fixed and mobile internet) the root cause was “System failures” (75 %).
  • Hardware failures were the most common cause of “Systems failures”, followed by software bugs.
  • Switches were the most frequent point of failure (e.g. routers and local exchange points) followed by mobile network home location registers.
  • Root cause third party failure incidents, mostly power supply failures, affected around 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 (mainly storms and heavy snowfall) lasted the longest: on average around 36 hours.
