8pm update – 13 June 2014
O2 have carried out a network update which should resolve this issue. To activate the update you may need to turn ‘flight mode’ on and off before refreshing the TfL website. After that it should work fine.
Please let us know if you still have any problems with this.
Reported Issues with O2
We’re seeing some issues when customers try to access our site over the O2 mobile network. If you are with another provider which uses the O2 mobile network you may have this problem too – for example on Tesco Mobile, Giffgaff and Lycamobile.
What’s the problem?
For some users the site does not load properly and key features cannot be used. You can tell if you are affected because the ‘menu’ button at the top of the page does not load and the ‘Plan a journey’ box will not open up when you touch it.
What should I do?
If you are being affected by this then using the link https://www.tfl.gov.uk will resolve it for now (the key bit being the ‘https’ part which switches to a secure connection).
When will it be fixed?
We are working with O2 to understand what is happening and to get it resolved as quickly as possible, whether that’s by making changes on our side or at the mobile network end of things.
Wifi usage is unaffected – the problem is only occurring when using a mobile connection.
If you are affected please let us know, we’re assessing how widespread the problem is.
