The O2 shop is busy - come back soon

What message do you give your online eCommerce customers when your site gets too busy?

Here's an example from mobile phone provider O2.

Oh, it should be noted that this wasn't midday during a sale / promotion or part-way through a new product launch, but around 11pm at night on a normal trading day...

How O2 is responding to critisism

Although I am currently suffering from having no mobile and data signal for around 7 hours now, it must be nothing compared to the stress O2 must be going through, given the network issues they have all afternoon and evening.

I therefore turned to Twitter tonight to see what is being said on that account. Take a look at this insult from an unhappy customer and the UK online service centre response.

Well done to O2 for being assertive and yet not patronising it it's response.
