Note: This post has been updated as of April 2nd, 10:00 p.m. PST.  The ROBLOX catalog and currency trading system are back online.  A small number (less than 0.01%) of ROBLOX accounts had some transactions rolled back.

We experienced a site issue the evening of April 1st that triggered alerts, and we intentionally took the site offline.  Two things happened prior to taking the site offline:

• Several assets were released from our backlog that were not ready for production
• Several accounts were incorrectly granted large amounts of ROBUX; some of these ROBUX were subsequently traded with other accounts

We brought the site back online during the late evening of April 1^st after ROBLOX team members patched several issues.

During the day of April 2^nd the site ran as normal, but we kept our catalog purchase and currency trading system offline as we audited and rolled back some recent transactions in a small number (fewer than 0.01%) of ROBLOX accounts. In cases where virtual items were traded for ROBUX that had incorrectly entered our system, we undid the trade and returned the virtual item.

Some of the assets that were released will remain in the ROBLOX catalog with updated pricing; however, we will be removing the assets that were not ready for release. In cases where non-production virtual items were unknowingly purchased, we undid the purchase and returned ROBUX to the account.

Today, we have deployed patches, developed tools to increase security and worked on plans to improve our response times. As an aside, ROBLOX uses PayPal for credit card processing, and does not store credit card numbers. If for any reason you feel your account was improperly returned to an earlier state, please contact customer service at [email protected]. Thank you very much to the ROBLOX community for all of your tips and suggestions during this busy day.
