Technical Issues from Nov, 8th, 7:30 CET to 10:00 CET

We recently experienced a temporary issue with our database management system (DBMS). The issue has been resolved, and we do not believe any data has been lost. However, as a precaution, we recommend the following actions:

• If you submitted solutions during the affected period, please consider resubmitting them to ensure they were properly received.
• If you created an account or updated your details, you may need to redo these actions.

We sincerely apologize for the inconvenience caused.

Technical Details (for those interested):

The issue arose due to an automatic update and restart of our virtual machine, which unexpectedly caused an outdated "ghost" database container to load alongside the current one. As a result, some requests were directed to the outdated container. While we are still investigating the exact cause, we have removed the outdated containers to prevent recurrence.

Thank you for your understanding as we navigate these unexpected challenges of hosting a competition!
