Transport for London (TfL) has blamed a software bug for causing several travel apps to report all London Underground lines were closed during the morning rush hour.
The issue meant that several of the most popular travel apps for smartphones were showing that all Underground lines, as well as the Overground, were running no services.
TfL’s social media pages were soon flooded with queries, while one app – Tube Map – sent out a notification to users confirming the bug and asking them to report any problems experienced.
The problem began around 8am according to reports, during the morning rush hour and one of the busiest times of the day for the Underground. TfL said the issue was reported to web developers and was fixed by 10am, after receiving messages from worried commuters on social media.
All tube lines showing as closed, technical glitch or has something happened? #london @tfl

The bug spread across several apps as TfL shares its service information with developers, who then use it to feed into their own apps.
According to the BBC, TfL initially said there was no problem with its feed, however this soon changed, with the firm saying it had been made aware of an issue which would be looked into.
Many were told to access TfL webpages in order to see “accurate” information.
