TomTom - the satellite navigation service - is offering its punters free traffic updates after its service was interrupted last month. The service interruption, which TomTom blames on problems with its ISP, follows similar problems in September, originally blamed on a server migration falling behind schedule. Both glitches affected TomTom's website and its TomTom Plus traffic update service.

The company declined to say how many of its customers had been hit by the snags but issued a statement this week in response to questions from The Register. It said: "TomTom`s ISP experienced two problems on their network causing the TomTom websites and the TomTom Plus services to be slow or even at some point inaccessible. This was in September and mid December. Although TomTom, in both cases, didn't hesitate to compensate all its users, TomTom truly regrets each and every problem and therefore measures have been taken to prevent these problems from happening in the future." ®
