Internet in Crimea is basically offline tonight. About 85% of it has been dark since 00:47 local time, now 5+ hours, after a major ongoing power outage across the peninsula.

Officials blame the blackout on an attack on energy infrastructure.

[WatchTheNet.com @watchthenetcom]

Most of Crimea's internet has been dark for 5 hours. Since 00:47 local time (21:47 UTC) only ~15% of the usual addresses answer. Simferopol, Sevastopol, Yalta, Feodosiya; ISPs Lancom, CrelCom, Sudak-Net and others. Routes stayed up in BGP.

Funny coincidence, last month i found out about a city called "Nederland" and now i'm flying right over it!! 👋👋🇳🇱

[Andree Toonk @atoonk]

Today I learned there's a city in Texas called "Nederland"
and apparently they just lost 70% of their Internet 🤠

Russia’s largest social media network under attack

[WatchTheNet.com @watchthenetcom]

VK (AS47541), Russia's largest social network, lost ~45% of its reachable network from ~03:45 Moscow time tonight. VK says drones attacked its data centre in Leningrad Oblast and that services work as normal. ~27% is still missing 2.5h later.

Russian-occupied Donetsk has lost most of its internet. Since 03:21 local time (00:21 UTC) the city's main ISP, Donbass Electronic Communications (AS20590), is down to ~15% of normal; the city as a whole to ~31%. Still down 30 min later.

Enjoying the autumn views in Vancouver. Loving the smell of the leaves and sound of the waves. 🍂🍁

@anurag_bhatia Wow nice. Also so @emot had an rpki post on hacker news today. Routing is hot today 🔥🚀

[WatchTheNet.com @watchthenetcom]

A week on, Yandex Cloud (AS200350) is still at about a third of its normal reachable addresses, flat since Oct 11. Two of its zones (Sasovo, Vladimir) are still down; Yandex's status page says "limited mode" and gives no recovery date.

@anurag_bhatia Impressive numbers !

[Andree Toonk @atoonk]

@bjorntopel That would be nice! are those improvements you're working on? or is it a config thing? curious, as ever 🤓

Uruguay: Maldonado department, home of Punta del Este, went largely offline at 16:08 local (19:08 UTC).

@heymingwei 🤩 geek eye candy

[Andree Toonk @atoonk]

Yandex still at 33% only, this is going to take while.
Yandex’s status page now mentions it will waive all of its fees for existing customers till end of the month

[WatchTheNet.com @watchthenetcom]

Yandex Cloud update (Oct 13): still running in "limited capacity". Yandex is now making all its Russian cloud services free for existing customers from Oct 8 to Oct 31.

Our data: only ~33% of its normal IP addresses answering, unchanged since Oct 11.

@tokifyi 👋 hi yes

[International Cyber Digest @IntCyberDigest]

‼️ BREAKING: Albert Heijn, the biggest Dutch supermarket chain, has halted online grocery deliveries after a cybersecurity incident.

It and its sister drugstore and liquor chains switched off their websites, apps and customer service.

In stores, shelf labels still show last week's discounts.

This is what it looks like when a country turns off mobile internet as drone defence. Fascinating to watch it show up in the data.

[WatchTheNet.com @watchthenetcom]

Drone defence on a Russian mobile network: MegaFon, one of Russia’s big three, was steady all week, then dropped ~40-50% four times in two days. Russia cuts mobile internet during drone alerts, as drones can navigate on cellular networks.

@osradar current state:
half its main availability zones are down. ru-central1-b (Sasovo) since 8 Oct, ru-central1-a (Vladimir) since yesterday What’s left runs on zones D and E. Gotta be hard to absorb: Yandex froze new capacity and is telling customers to move to other providers

[Andree Toonk @atoonk]

the two Yandex Cloud zones still up aren’t far from the strikes. ru-central1-d reportedly runs from Kaluga, hit on 9 Oct. ru-central1-e, launched in March, sits right next to Vladimir: Yandex says it’s under 1 ms from zone a, with its own power and network.

two of its main Availability zones are now completely down 🤯

[Andree Toonk @atoonk]

Holy crap! Another yandex data center attacked just now. That’s now 2 regions offline. Only 30% of responding IP addresses remaining. This is going to be a big issue!

[WatchTheNet.com @watchthenetcom]

Yandex Cloud (AS200350) dropped again: since 04:53 Moscow time it lost over half of what was still answering after the 8 Oct hit. Its status page lists a power disruption in a second zone, ru-central1-a, with 84 services unavailable.
