RIPE Atlas probe connectivity drop around 11:20 UTC — looking for community insights
Hello everyone, I have recently been exploring RIPE Atlas’s public data, focusing on probe connectivity. Yesterday, I noticed a sharp drop in the number of connected probes, particularly around 11:20 UTC. As I am new to working with this data, I would appreciate your help understanding this observation. Did these disconnections actually occur simultaneously, or could the pattern reflect how the data is collected, reported, or processed in my dashboard? To make the results easier to explore, I have put together a standalone version of the dashboard, available here: https://ripleatlas.netlify.app/ It includes an interactive timeline that lets you explore the data and examine the changes I observed. My goal is to validate my interpretation and improve the dashboard’s logic so it can better distinguish actual connectivity events from potential data artifacts. Any insights, suggestions, or feedback on the methodology or dashboard would be greatly appreciated. Thank you for your time and help! Best regards, Dixán

Given that my probe disconnected at this time, but there was no connectivity issue at my side, this seems very likely to have been an Atlas infrastructure glitch.
"Your probe 928 has been disconnected from the RIPE Atlas infrastructure since 2026-09-16 11:22:14 UTC"

Hi Dixán, There was indeed an incident that caused many hardware probes to disconnect on Thursday. The root cause was identified fairly quickly and the vast majority of the probes had reconnected within 3-4 hours. Usually in cases like this we would create a status page entry ( https://status.ripe.net/) but in this case we overlooked to do so. Apologies for the lack of communication on this. Kind regards, Chris Amin RIPE NCC On Fri, 18 Sept 2026 at 16:25, Dixan Santiesteban <dixan2024@gmail.com> wrote:
