Nearly half of all Dublin Bike stations around the city were not working yesterday evening following a ‘connection issue’.
A spokesperson for Dublin Bikes said the issue, which affected 41 sites throughout the city, was down to a "connection issue".
However, the issue was resolved last night.
"All sites are now fully operational," a spokesperson for Dublin City Council has said.
Users of the service took to Twitter to vent their frustrations last night.
"Lots of #DublinBikes stations out of order Could not get a bike earlier. Any explanation there folks?," wrote one.
Another wrote: "Just lost an hour of my evening finding a docking space for a bike. All full. Anyone home at Dublin bikes?"
There are now just over 100 Dublin Bike stations across the city and the public bicycle rental service was set up in 2009.
