Is LucidLink Down?

This issue was resolved with the release of the updated clients on October 23rd. --- [2026-10-26T08:49:48.825Z] (monitoring) We are continuing to monitor for any further issues. --- [2026-10-26T08:49:08.963Z] (monitoring) What's new Following our earlier advisory (https://status.lucidlink.com/incidents/pyrcv6319vn6) about the eMudhra certificate issue, we have released updated LucidLink desktop clients that remove the affected third-party certificates from the client's list of trusted certificate authorities. We recommend that you install the update as soon as you are able. Available downloads Patches are now available on the [LucidLink Downloads](https://www.lucidlink.com/download) page for LucidLink 2.x and 3.x clients as well as mobile app stores. What to do next Please update all LucidLink desktop and mobile clients to the latest versions, and if you have any issues, please use the links below to get in touch. If you have questions As always, the LucidLink status page (https://status.lucidlink.com) and support portal for LucidLink 3.x (https://support.lucidlink.com) and LucidLink Classic / 2.X (https://support-classic.lucidlink.com) are available if you need additional information or assistance. Thank you for being a LucidLink customer and for your prompt attention to this update. Sincerely, LucidLink Engineering --- [2026-10-23T17:17:28.654Z] (monitoring) What happened This week, security researchers disclosed that eight certificates issued by eMudhra, a third-party certificate authority (CA), were created with weak cryptographic keys. eMudhra has revoked them, and Google, Mozilla, and Apple have removed trust in them. Like other software that bundles its own list of trusted CAs, the LucidLink desktop client needs an update. LucidLink’s servers and infrastructure are not affected. How it relates to LucidLink The LucidLink desktop client includes its own list of trusted certificate authorities. In theory, an attacker positioned on your network connection who had forged one of these certificates could attempt to impersonate a server to an out-of-date client. We have seen no indication that it has been attempted against LucidLink or our customers. What are we doing LucidLink is actively working to remove the affected third-party certificates from both LucidLink 2.x / Classic and LucidLink 3.x. We will release updated desktop clients as soon as our test process is complete, likely this weekend. What’s next We appreciate your partnership and we are committed to maintaining your trust. Please look out for a follow up email as our team works to deliver this patch asap. As always, you have access to the LucidLink status page and our support team if you need additional assistance. We will be back in touch shortly when fixes are available. Sincerely, Gregory Tomczyk VP of Security

This incident has been resolved. --- [2026-09-02T21:40:01.305Z] (monitoring) We are continuing to monitor for any further issues. --- [2026-09-02T21:39:44.061Z] (monitoring) All LucidLink services are operational. The connectivity disruption identified earlier is related to the external Cogent Communications network incident and is not caused by LucidLink infrastructure. Cogent Communications continues to provide updates on the incident here: https://ecogent.cogentco.com/network-status Some previously affected customers have reported restored connectivity. Customers who continue to experience connectivity issues are advised to contact their Internet Service Provider, as the issue may be related to network routing through Cogent or other upstream providers. We are continuing to monitor customer connectivity and the progress of the Cogent network recovery and will provide further updates if there are any significant changes. --- [2026-09-02T18:38:57.040Z] (identified) LucidLink has investigated and identified a service disruption in the Southwestern US region, with clients unable to connect to LucidLink infrastructure. Although this outage does affect the client routes to the LucidLink infrastructure, the data in the LucidLink Filespaces is not at risk. It has been determined that this disruption has been caused by a service incident with Cogent Communications and their network infrastructure. Here is the information from Cogent Communications on their status page: https://ecogent.cogentco.com/network-status Customers in the Los Angeles and Southwestern United States areas may be experiencing increased latency and/or service disruptions due to two separate fiber cuts. Transoceanic traffic to certain Asia-Pacific regions may also be affected. Cogent Engineers are currently being dispatched to both locations, and our third-party fiber vendor has also been engaged to assist with restoration efforts. There is no ETR at this time. We will continue to update here as we have more information.

We are monitoring intermittent access issues affecting a limited number of LucidLink filespaces using Wasabi object storage. Affected customers may experience connection errors, interrupted or partial file transfers, or brief difficulty accessing their filespace. Wasabi has linked these recent cases to their scheduled infrastructure maintenance affecting subsets of storage resources. Wasabi has advised that these conditions are temporary and that service should recover automatically once the affected maintenance is complete. While previously affected filespaces have recovered, we continue to receive isolated reports. We are working with Wasabi and monitoring for further impact.
