Sweden-Latvia Internet cable was reportedly cut on 26 January. @meileaben reports that packet delays between selected #RIPEAtlas anchors increased by 5-20ms at around 00:45 UTC.
However, no packet loss was observed, suggesting that the Internet successfully routed around the damage.

The double undersea cable cuts in the Baltic sea have been in the news over the weekend. But what was the impact on the Internet?
Emile Aben (@meileaben) and Alun Davies take a look at what #RIPEAtlas can tell us about this incident:https://labs.ripe.net/author/emileaben/does-the-internet-route-around-damage-baltic-sea-cable-cuts/

"In November, we shared our preliminary analysis of the analysis of the Baltic Sea cable cuts. Digging into the results of ping mesh measurements routinely performed by RIPE Atlas anchors, we were able to provide an initial sketch of how this affected connectivity between the countries at both ends of both cables."
Emile Aben, Jim Cowie and Alun Davies delve further into the Baltic Sea cable cuts on #RIPELabs #RIPEAtlas

TIL: The red square on a LinkedIn name is not a standard platform feature but a symbol used by some users to show solidarity with the Dutch academic community's protest against cuts to higher education funding. By adding the red square after their name, individuals are signaling their opposition to austerity measures affecting universities and other knowledge-based institutions.

This is how #RIPEAtlas saw the #Starlink #outage. Steep drop in connected probes, but interestingly there seem to be probes on starlink that kept their connectivity to our infrastructure, which would suggest that it was not a full outage of the starlink system.

Connectivity of #RIPEAtlas probes in #Iran in the last few days:
* Since 13 June connectivity is much more volatile. Shift happened between 14:00-15:00 UTC
* Since 18 June there are only 6 connected probes left. Most others disconnected before 13:00 UTC -

I heard rumors about an IXP issue in Italy on May 11 at night.
The #RIPEAtlas anchor mesh latencies did see some paths with increased latency starting a bit before 22:00 UTC (midnight in #Italy ) -
Next week is #RIPE90 week! I will attend Wednesday through Friday, so hit me up if you want to talk about Internet outages, Internet resiliency, Internet measurement (#RIPEAtlas, #RIS), Internet live streaming of lettuces.
For netops from #Spain and #Portugal : I'm really curious about your stories on how you dealt with the grid outage on 28 April. I would love to see how these stories connect up with the data we collected about the event.

The number of connected #RIPEAtlas probes in #Chile showed a steep drop after a massive power outage ( https://www.reuters.com/world/americas/power-outage-hits-vast-swaths-chile-largest-copper-mine-santiago-streets-2025-02-25/ )

Quick look at #RIPEAtlas mesh pings on 26 Jan, shows some (not all!) #Finland-#Lithuania anchor pairs saw:
* A noticeable latency increase (5-20ms extra) around 00:45UTC, in line with the reported cable cut of the LVRTC-cable around that time.
* No noticeable changes in packet loss.Looks like another one where the Internet managed to route around damage.

On a #FrecciaRossa (must be Italian for f*ing fast train) between Milano and Roma.
Can't help but measure its Internet, one thing I noticed is that COLT (AS8220) providers internet connectivity for onboard free wifi, and on all 3 devices I checked the external IP is the same. So maybe the whole train is on a single IPv4 address at 300km/h?
Kudos #BGPtools for having this on the front page, so it was a breeze to ask my 12yo to check this!

We did a deep dive into the Baltic Sea cable cuts, looking at the different levels of resiliency of the Internet in action. I hope it will provide for interesting christmas holiday reading 🙃

In the news: Cable cuts this morning between #Sweden and #Finland ( https://apnews.com/article/sweden-finland-damaged-cable-9b6092fd670383a4de28f05c33405768 ), so I looked into what #RIPEatlas sees. We do see a noticeable increase for a few paths between anchors in FI and SE at 3:15AM UTC (roughly 5% of paths), and some interesting changes in packet loss.
Does the timing of state changes in these graphs (3:15 for latency increase, and also 6:00, 11:00 for pkt loss, all UTC) coincide with timings of the cable cuts?

I expected some blocked paths on my bicycle ride from #Haarlem to #Amsterdam, but surprised by how cleaned up bike paths are the day heavy #summerstorm #Poly .
#Halfweg not clean but not bad either
#Westerpark is very clean
#DeBretten all cleaned up
