A server error affected the O2 networks for hours, many people have not been able to make calls since the afternoon, and some emergency numbers cannot be reached. In the late evening the all clear is given.
The massive restrictions in O2’s mobile and fixed networks have largely been resolved. A company spokesman said in the evening that the technicians had stabilized the network and restored availability apart from a few rework. The disruption was “almost completely resolved”. Deutsche Telekom reported no disruptions. A Vodafone spokesman said there were only slight restrictions on LTE telephony in its own network. However, these are not a problem for customers because their calls are then controlled via the GSM (2G) network.
Several state authorities also gave the all-clear. It was reported from Berlin that there were no longer any known disruptions to the capital. The fire brigade in Bremen reported that the impairments were largely resolved, “partially resolved,” said the police in Hamburg. The authorities had previously warned of the failure of the emergency call to the fire brigade and police.
Cell phone calls in the O2 network were temporarily not possible for some users on Thursday. According to the company, the reason was a fault on a voice transmission server. According to the information, a large part of the telephone calls could be transmitted via other servers. Calls with apps like Whatsapp were possible via data transfer servers.
On Thursday afternoon, around 19,500 users reported problems in the O2 network on the allestoerungen.de portal. Later, the number of fault reports from mobile phone users fell significantly. At the same time, allestoerungen.de also reported alleged outages at Vodafone and Telekom, although by no means as strong as at O2. The reason for this may have been that Vodafone and Telekom customers called someone in the O2 network and thought that the lack of connection was due to their own network – but in fact the network problems at O2 were the reason. “We very much regret the resulting inconvenience,” said the O2 spokesman.
