Registrations for Virgin Media's London Underground wifi network were up 50 percent on Tuesday as commuters stood waiting on tube platforms during delays.
Typically, traffic on the network peaks at around 8.35am but hit its high twenty minutes later as disgruntled passengers "searched for travel updates to keep work colleagues and friends updated with emails, Tweets and Facebook posts", a spokesperson for Virgin Media said.
Certain services including TfL travel information and London entertainment and news for free through Virgin Media's wifi portal.
Wholesale deals with EE, O2 and Vodafone mean the majority of Londoners can get full access to the internet, such as using Google, at no extra cost. However passengers using other service providers pay £2-per-day or £5-per-week.
A total of 137 of London Underground's 270 tube stations are connected to wifi from Virgin Media, which plans to roll out connections to the remaining stations in the summer.
More than 800,000 devices are currently registered to use wifi on the London Underground, sending an average of one million emails, web pages, Tweets and Facebook posts underground every week day.
Last week Virgin revealed that traffic from BlackBerry devices has doubled over the past year, however the gap between iOS and Android usage on the network is narrowing, with 65 percent of web page views coming from iOS devices and 30 percent from Android devices, compared to a 74 percent to 20 percent ratio last year.
