Summary of impact:
At approximately 06:39 UTC on 3rd January 2023, our domain registrar disabled the ddlnk.net domain without notice due to receiving abuse reports. We restored services at 12:00 UTC on 3rd January 2023.
During this time, any customers who don’t use their own branded domain for emails, may have experienced the following issues:
Root Cause:
The domain ddlnk.net was disabled by our domain registrar after receiving abuse reports. We didn’t receive prior notice before our domain registrar disabled ddlnk.net. We’re waiting for more information from our domain registrar on the nature and source of these reports.
Our platform provides link tracking and forwarding of links to URLs on the internet. Our customers and trialists can add links in their emails and SMS that may forward to URLs hosting unwanted content, malware or viruses. As the domain ddlink.net is used for email link tracking and forwarding, an unsafe URL being added to an email campaign could trigger abuse complaints to our domain registrar. Our Messaging Compliance Team proactively monitor abuse complaints for unsafe URLs and prevent those accounts from sending. This activity stops the majority of unsafe links from being used.
Mitigation:
The timeline (in UTC) for resolving this issue was:
Next Steps:
In order to prevent this issue from happening again, we’ll continue to work with our registrar to understand why the domain was suspended and why we were not notified prior to this happening.
