It might be the summer bank holiday across most of the UK, but at least two services to aid travellers are unavailable this Friday afternoon.

Anyone trying to add credit to their Oyster card on the Transport for London website is out of luck. The page says: "Important site maintenance means Oyster Online is temporarily unavailable". The page has been unchanged all day.

We called Transport for London (TfL) this morning, but no word yet.

Meanwhile, anyone trying to update the information on their TomTom GPS is also out of luck. A message there reads: "The TomTom PLUS section is currently unavailable due to maintenance. Our apologies for the inconvenience. Please try again later."

A Reg reader who told us about the problems said: "I bought a TomTom 520 from Halfords today for the long weekend - the guy in the shop said it was the fortieth they'd sold today. So loads of people must be having problems."

To be fair to TomTom, a charming spokeswoman told us the firm was sorry for the problems caused by migrating servers and asked us for the details of the Reg reader who was having trouble so they could try and help him out. (Take the next left after the roundabout, that sort of thing?)

TfL is here and TomTom is here.

Happy bank holiday to readers in England, Wales, and Northern Ireland. ®
