We are currently investigating an issue causing delays with Siteimprove’s crawler and link checker processing. Sites are successfully entering the scan queue; however, some scans are taking longer than expected to complete. As a result, Digital Certainty Index (DCI) scores and related metrics may be delayed in updating. Our development team is aware of the issue and is actively working to restore normal processing. We will continue to provide updates here as more information becomes available.

We have identified the issue causing delays with Siteimprove’s crawler and link checker processing, and a fix has been applied. Processing has resumed, and we are currently working through the remaining backlog. Sites are continuing to enter the scan queue successfully, but some scans may still take longer than expected to complete while the queue catches up. As a result, Digital Certainty Index (DCI) scores and related metrics may still be delayed in updating. We appreciate your patience while we continue working toward full recovery.

Degraded Performance - Crawler
Affected: Crawler
Timeline · 7 updates
- investigating Mar 03, 2026, 12:46 PM UTC
We’re investigating an issue impacting crawl processing and ingestion, which may result in delayed crawl starts and delayed crawl completions for a subset of customers. You may also see unusual crawl status updates in crawl history while processing catches up.
- investigating Mar 04, 2026, 12:09 PM UTC
We’re continuing to investigate the cause of the backlog. To restore processing times, we’ve taken steps to reduce incoming workload and increase capacity to process the existing queue. As a result, some ongoing crawls may run more slowly than usual while we work through the backlog. We’re actively monitoring performance and making adjustments as needed to keep recovery moving in the right direction.
- investigating Mar 05, 2026, 12:06 PM UTC
We’re continuing to investigate an issue where temporary outages led to queue build-ups due to resource constraints. We’re actively working to restore normal operations and clear the backlog.
- investigating Mar 06, 2026, 01:54 PM UTC
We’re continuing to investigate an issue affecting crawl processing, which has resulted in delays to crawl starts and completions for some customers. We’ve made steady progress and have started to see some previously affected sites queue, process, and finish scanning successfully, with conditions beginning to stabilize. However, we’re still working on a longer-term fix to ensure all affected sites are queueing and processing correctly. We’re actively monitoring performance and making adjustments as needed. Thank you for your patience as we work to restore normal operations.
