Interruptions caused by the weather: Ongoing improvements

24 August 2005

Some 13,000 phone connections are still out of service in the areas affected by the rainy weather. Specialists from Swisscom Fixnet and Swisscom Mobile are working around the clock wherever access to damaged sites is possible.

Helicopters are flying in replacement material as necessary. The flooded cable and exchange infrastructure, hardware defects and power cuts are still the main reasons for the various interruptions in phone service in the affected areas.

Swisscom Fixnet

In the Bernese Oberland, exchanges in Oey Latterbach, Boenigen and Wilderswil are still flooded. The exchanges in Zwischenflüh and Lauterbrunnen-Wengen still have no electricity. The Iseltwald exchange also has problems with its power supply. The disruption is affecting some 4,300 connections.

In central Switzerland the following exchanges are still not operating: Grundhof (Emmenbrücke LU), Melchtal (OW), Neuschwändi (Engelberg OW), Melchsee-Frutt (OW), Unterschächen (UR), Rynacht (near Schattdorf UR) and Bristen (UR). A total of 1,800 connections are still out of service.

In eastern Switzerland, the Weesen (SG) exchange has been provisionally repaired. Around 150 broadband connections are out of service. In Landwassertal, another 950 broadband connections have been severed by damage to fibre optic cable.

Swisscom Mobile

Specialists from Swisscom Mobile are working under heavy pressure to repair damage to the mobile network that was caused by the weather. Mobile coverage has been restored to certain areas, and normal operation is gradually resuming. The crisis team from Swisscom Mobile continues to work closely with authorities to identify any other potential flood areas, so that they can take preventive measures as necessary. In areas with mobile service, the system may become overloaded. The public is therefore being asked to use mobile phones sparingly so that sufficient capacity will remain for rescue communications.

Emergency calls (112) can be placed via mobile phone if at least one of the three Swiss mobile networks is available.

Currently limited or no access to the Swisscom Mobile network is available in the following communities:


- Zwischenflüh
- Lauterbrunnen
- Wengen
- Gimmelwald
- Entschwil
- Thun


- Hergiswil
- Melchseefrutt


- Serneus
