Update – Lead Import Functionality Restored (Monitoring Ongoing)

Our previous update was a bit fast due to lack of sleep. We are not planning to close down Adversus for maintenance this evening. Issue should be resolved.

Lead uploads through manual import, API, and Journey are now functioning again. We have tested the solution and confirmed that core functionality has been restored.

At the time we communicated an expected resolution time of 24 hours, the approach we are now using had not yet been discovered. During the night, we identified and implemented an alternative solution, allowing us to adjust the database logic and make use of previously skipped ID ranges caused by the earlier issue. This has enabled us to bring lead import functionality back online earlier than anticipated.

The previously announced database capacity upgrade is still continuing in the background as an added safeguard.

What this means for you:

• Lead uploads through manual import, API, and Journey should now work as expected
• There may still be isolated edge cases, which we’ll address as they arise
• To avoid potential load-related issues, we recommend splitting large uploads rather than sending everything at once

If you encounter any unexpected behavior, please report it to our support team so we can investigate and follow up promptly. We’re continuing to monitor the system closely and will provide further updates here if needed.

A formal incident report will, of course, be created and can be shared upon request once finalized.

We sincerely apologize for the inconvenience this has caused and appreciate your patience and understanding throughout the process.

Update – Lead Import Functionality Still Affected, Full Resolution in Progress

Since Wednesday, we’ve been investigating issues affecting lead uploads and the creation of new contacts in Adversus. The initial problem was traced to a depletion of available IDs in the database. A mitigation was applied, and based on early tests, the system appeared to be stable.

However, new error reports emerged earlier today, showing that the issue persisted. In hindsight, our initial confirmation was premature, and we acknowledge that the problem had not been fully resolved. We appreciate your patience as we work through this in a transparent and thorough manner.

We’ve now identified the root cause as a highly rare edge case, where under very specific conditions, a bug could cause the system to jump 30,000 to 50,000 IDs at a time. This led to a much faster-than-expected exhaustion of ID capacity in the database.

It’s worth emphasizing that the existing database setup was fully sufficient under normal usage patterns. However, to ensure ongoing reliability and prevent this from occurring again, we are now upgrading the database to significantly expand ID capacity.

This upgrade process is expected to take up to 24 hours.

What this means for you:

• The Adversus platform will be available again from tomorrow at 08:00 CEST
• Lead upload and new contact creation will remain unavailable until the upgrade is complete
• All other functionalities will work as normal from 08:00 CEST

We understand this situation is frustrating and are doing everything we can to resolve it as quickly and safely as possible. We’ll continue to post updates here as progress is made.

Thank you for your continued patience and support.

The maintenance on the import system is still in progress. While we’re not yet ready to share the full update originally planned for 22:00 CEST, we expect to provide that update within the next 30 minutes.

Thank you for your continued patience — we’ll be back with more information as soon as possible here on status.adversus.io.

As part of our ongoing effort to resolve the lead import issue, we will be performing targeted maintenance on the import system. This requires us to temporarily shut down access to Adversus from 21:00 CEST.

This step is necessary to implement a permanent fix to the lead upload functionality.

We will provide an update by 22:00 CEST with more information on expected completion time, right here on status.adversus.io.

Please note:

• The platform will be unavailable starting at 21:00 CEST
• This maintenance is specifically related to lead upload and import functionality

Thank you for your patience as we work to restore full functionality. We'll continue to keep you informed here.

We are still experiencing an outage affecting the import system. Although service briefly resumed yesterday, the issue has reoccurred, and the import system is currently not operational.

The root cause has been identified, and we are now working on a permanent mitigation. Please note that this work is expected to take the remainder of the day.

In the meantime:

• Adding previously existing contacts to campaigns still works as a temporary workaround
• Uploading new leads via UI or API remains unavailable
• Any actions performed through the Warehouse during this period cannot be reversed, so please proceed with caution

We understand the impact this has and sincerely apologize for the ongoing disruption. We'll continue to provide timely updates as we make progress.

Thank you for your patience.
