Webshrinker outage history

Our engineering team has identified an issue that is causing the dashboard to not reflect changes correctly within the UI and is currently working to implement a fix to remediate the problem. Changes are active and working as expected. There's currently a delay of up to 30 minutes before they show in the dashboard, so what you're seeing may not reflect the latest updates yet. We will provide updated status as soon as possible once a fix has been implemented.

We are continuing to work on a fix for this issue.

A fix has been implemented and we are monitoring the results.

This incident has been resolved.

Our engineering team is currently investigating an issue that is causing DNS resolution to be Intermittent across the UK region and is currently working with our partners to resolve the situation.

Resolution is back in and working; engineering is monitoring.

Our connectivity is provided through an Internet Exchange (IX), essentially a shared hub that connects us with many other networks. If our own connection to the IX had gone down, it would have affected all customers equally, but that wasn't the case here. Based on what we're seeing, it's possible that a subset of networks sharing the same infrastructure at the IX experienced a localized issue, which would explain why only some customers noticed a problem while others didn't. We want to be transparent that this is our best working theory rather than a confirmed root cause, as we don't have full visibility into that specific piece of infrastructure. We also checked with our upstream provider, and they've confirmed that all systems on their end showed as healthy throughout this period. We're continuing to monitor closely, and we'll update you if we learn anything further. Please let us know if you're still experiencing any issues.

Traffic redirection has been completed, and we’ve shifted traffic to the closest available region. Performance should now be returning to normal, if it hasn’t stabilized already. We will continue to monitor closely to ensure stability.

This incident is now resolved. We have now shifted traffic back to the NYC region. This issue was identified to be caused by a routing problem at an upstream Internet Exchange provider, which impacted connectivity and cascaded to our services. To minimize customer impact, we temporarily rerouted traffic to our Washington, DC region. Once the issue was confirmed to be resolved by our upstream partner, traffic was safely restored to the NYC region.
