At 23:00 UTC, it was confirmed that the incident had impacted three links: Marseille-Lyon, Marseille-Milano, and Marseille-Barcelona.
At 01:00 UTC today, when Zscaler’s repair crews restored one of the links, but the technicians continued observing packet losses and latency for some destinations.
At 18:58:01 UTC, Zscaler posted a final update stating the issue has been resolved.
“This incident has been resolved. Please contact Zscaler Support if you have additional questions.” - Zscaler.
I received the following question off-board from etagordon. I had the same unspoken question so I thought I should post it on the board. Here’s what he wrote:
“I currently have a question about one post, concerning Zscaler repairing a severed cable. I am wondering what Zscaler has to do with repair of cable or optic fiber. Seems far out of the company 's lane.”
That sounds way, WAY, out of Zscaler’s lane to me too, and if that’s one of their jobs it would be a big negative for me. Do any of you techie’s have an explanation or a different view?

They are not repairing the cable they are monitoring the traffic. When the cable came back on line they restored the link in their Computer interface. Problem solved.

How is subsea cable repaired? (onesteppower.com)
Cool pics in this article about how.
There are a few different repair companies that exist, but I couldn’t find a link between them and Zscaler.
“I currently have a question about one post, concerning Zscaler repairing a severed cable. I am wondering what Zscaler has to do with repair of cable or optic fiber. Seems far out of the company 's lane.”
I blame that Bleeping Computer article for all the confusion here, as they clearly made it seem like Zscaler is doing the repair of the cable itself. That is not at all the case.
As others have mentioned, Zscaler isn’t doing any repair nor is it responsible for the undersea cable in any way. Zscaler discovered the issue (seeing a huge chunk of its south of France traffic drop off), and its posts & actions were about routing any traffic going through Zscaler’s platform around the problematic areas of the Internet. Once the issue was resolved, ZS then removed those routing fixes.
The CEO post had this helpful map showing how crucial that area is for sub-sea cables from Africa and Asia coming into EU.
Remember that Zscaler uses the Internet as its networking backbone, so it sees these things quickly. I am a bit surprised about the lack of press these sub-sea cable issues are getting with 2 this week (S of France and 2 diff ones in Scotland), both showing signs of tampering. Combine that with the Nord Stream pipeline sabotage in Sweden a month ago – clearly are some major regional security implecations for the EU.
