November 1st, iRacing Maintenance Release Notes

This maintenance will affect all iRacing services, including all Race Server environments, the iRacing.com Membersite, and the iRacing BETA Interface. Members will be unable host or join sessions during the downtime, and any sessions in progress at the start of the downtime will be terminated. 

This maintenance period will be used to perform another round of crucial work on the US Race Server and iRacing data center relocation project. Our database will be switched over to our backup, already at the new location, and then re-deployed to the new infrastructure at the new location. If all goes well, we anticipate this is the final major outage remaining to complete this move. 

We anticipate this downtime to be completed within 6 hours, however, it may take additional time after the iRacing services are back online to stabilize the user experience. 

The Test Drive iRacing service is already online and available.


 

October 29th, iRacing Maintenance Release Notes

This maintenance period will be used to perform crucial work on the US Race Server and iRacing data center relocation project. Nearly all race infrastructure will be transitioned to a new data center. As part of this work, we’ll be decommissioning our current US Race Server farm and creating a new one. Most of this infrastructure is already in place at the new data center, but we’ll be adding some critical networking gear that will help us better control routing between members and this new server farm. We’ll also be doing database work to remap Sessions and Seasons to the new farm. This is a significant milestone for us. There is still much more work that will continue to be done behind the scenes after these steps are complete. If all goes well, we anticipate only one additional major outage remaining to complete this move.
