Update - The changes that were deployed yesterday made a positive impact. We are now seeing registration data come back for the vast majority of domains. However, additional work is needed to increase the domain coverage further and re-enable email alerts for continuous seed discovery. Censys is investigating additional changes with our upstream data provider to provide this.

Identified - We have seen significant improvements to registration information accuracy for a large portion of customer domains. This has been accomplished by working with one of our upstream data providers to better handle rate limiting. However, we are continuing to see data problems with a different subset of customer domains. Censys is testing a set of fixes to resolve these data problems. We will be providing an update tomorrow on the success of these fixes and if additional improvements are needed.

Update - Censys is now supporting both WHOIS and RDAP data, reducing the impact to seed discovery. However, intermittent data is still being returned for some domains. Censys is working to resolve the data gaps with our upstream provider. For now, valid domains without WHOIS and RDAP registration data are being preserved in the inventory.

Update - The WHOIS servers operated by an upstream provider remain unresponsive, causing continuous seed discovery in Censys ASM to remove or fail to re-confirm domains registered through that provider.
To prevent any further disruptions, we’ve temporarily suspended continuous seed discovery while we implement an interim solution and engage with the upstream provider. We are actively monitoring the situation

Investigating - The WHOIS servers operated by an upstream provider have been unresponsive, causing continuous seed discovery in Censys ASM to remove or fail to re-confirm domains registered through the provider. As a result, customers whose seed inventories depend on those WHOIS lookups may see those seeds temporarily dropped from their inventory.
