UK.gov's online IT services catalogue Cloud Store was downed by an error during a scheduled update by platform provider Procserve, The Channel understands.
An outage occurred yesterday morning that prevented suppliers from logging into the portal and public sector IT heads from searching for the requisite services.
The web shop was back up and running from 8am today a Cabinet Office spokesman confirmed.
"G-Cloud is operating normally again and the Cloud Store is open for business," he said.
Sources suggested the glitch happened as Procserve was updating the classification view but further technical details are not available at this time.
This is not the first time Cloud Store has encountered operational issues since its February launch - just days after its release some of the 257 accredited suppliers on it could not tweak their entries.
Then after less than two weeks the catalogue was disrupted as Microsoft's Azure platform went missing in action for eight hours.
Procserve was unavailable to comment. ®
