Yup loads of post RS errors and T3 timeouts. 

Check first for local faults on 0800 561 0061 and ensure all cables and connections are tight and secure.

Hi @ne, thank you for your response.

We're sorry to see it's got worse 😔

In order to look into this for you further, we'll send you a private message on here. 

Look out for the envelope in the top right-hand corner. If you're on a portable device with a smaller screen, click on the icon in the top right-hand corner and select "messages" from the additional menu options.

Regards,
Daniel
