⚠️ Confirmed: Network data show a national scale internet outage in Spain, with nearby countries including Portugal and France also affected; the incident is attributed to a regional power outage impacting multiple countries 📉🔌
⚠️ Update: Analysis of traffic data in #Portugal shows the ongoing impact of today's power outage on critical infrastructure; Portuguese grid operator REN has attributed the blackout to a fault in Spain's power grid due to a "rare atmospheric phenomenon"
⚠️ Update: Metrics show a corresponding decline in internet connectivity in Morocco, with operator Orange Maroc confirming the telecoms disruption is linked to the ongoing Europe power blackout that has knocked Spain and Portugal largely offline

@netblocks
Ad "REN has attributed this to a fault due to a rare atmospheric phenomenom":

This is false. It has been denied, not attributed. See:

Spain, Portugal and parts of France hit by massive power outage

A nationwide power outage hit Spain and Portugal on Monday, leaving millions without electricity. Reports indicate issues with the European electric grid. This is what we know. #EuropeNews

@JeGr
Thank you for the clarification.

Apparently the whole grid collapsed, at least in Portugal, and a complete black start is needed, so it's going to take a while until everything is running again.

Martin is in Spain on site and apparently regions come back now piece by piece. So hopefully Portugal will get back the same way.

#barcelona has electricity again! You can hear cheering on the streets. Outage was 6 hours and 14 minutes.

@JeGr
Vila Real (in the North of Portugal, low load) has since gotten power.

My area should be one of the last, because it's near the capital and we'll put quite a strain on the network.

Hopefully it won't be too much longer.

@nanianmichaels
Fingers crossed! Best wishes to you and the whole region for a fast recovery!
@nanianmichaels @JeGr Power in Faro (Algarve) was back at 22.10 local time, there was loud cheering from streets and balconies when lights switched back on 😊

@sico93 Now if only DIGI decided to bring their network back up...

Still no phone for me, and no way to contact them, because their support number is... a DIGI number, with no landline number available... *SIGH*

@JeGr @netblocks REN did tell Sky News that the blackout was linked to a "rare atmospheric phenomenon" affecting Spain’s grid. Not sure it’s accurate to say they denied it entirely, there might be conflicting reports but initial attribution was made.

'Rare atmospheric phenomenon' behind huge outages in Portugal and Spain

Thanks, not entirely sure about the reports on either end. The Intel about a fire seems mixed up with another power loss from last year so we'll probably have to wait and see what the real root causes have been. Press and news outlets seem very much like too much speculation and less fact checking it seems :/ Not a good thing in such a situation where we don't need drama but cool heads and proper information.

@JeGr I think you got completely Ignored even though you're correct
@netblocks Network come and go now at Valencia Spain, but the power out its almost 5 hours now 😭

@netblocks
As someone in Portugal, can confirm, the whole country has no power.

Most internet networks are still up, as long as you're on a mobile network or have a generator to power your devices (source: currently using my fixed ISP's connection using V2L).

Weirdly enough, even voice calls are failing, mobile data has been much more stable than voice.

This is the kind of chart you’d expect to see in a series like Zero Day or Apagón but it’s real.

This wasn’t a cyberattack, a war or a natural disaster. Just one fault and suddenly entire countries are blinking offline.

This shows how fragile these systems really are. Even advanced, interconnected systems remain deeply vulnerable to cascading failures.

It's a reminder that we’re always one bad day away from blackout...

@isik5 Is it possible to see these graphs somewhere on the netblocks site?
