The system of mobile services provider Telenor crashed for hours last Tuesday, most likely because of a faulty power supply unit.
The most-serious effects were in Budapest, where a considerable percentage of users were unable to make phone calls and the website and customer service were unavailable. Within some 60 minutes of the first reports, most of the company’s clients were again able to phone but for many it took hours more before full service returned. The last time a similar thing happened in Hungary was in December 2009 when a software update caused T-Mobile’s service to shut down in certain areas. T-Mobile gave 10 extra minutes to users affected by the problem. According to Telenor’s service terms, the company must pay indemnity if the service is unavailable for more than four hours.
