Knopflerfish is now available again

The Knopflerfish site is now available again and we apologize for the inconvenience this may have caused.

The problem was that some rats deep under the streets of Gothenburg decided for a fiber rich diet. A large section of our internet cable is now replaced.

 If anyone encounters any problems or errors please report back to us.

Knopflerfish site is temporarily unavailable

The Knopflerfish web site is temporarily unavailable. This is due to a broken fiber connection to the Makewave office. We hope to have everything sorted out later today.

Our apologies for the inconvenience.

Regards,
Christer
