This is the 8th time ENISA publishes an annual incident report for the telecom sector. In 2018, half of the total user hours lost (482 million user hours) were due to natural phenomena. It is the first year that natural phenomena are the main root cause category in this respect, accounting for more user hours lost than the category of system failures.
