Yesterday, Telia, one of Swedens biggest telecom provider, went offline and wasn't fully back until 3,5 hours later.
The reason for the fault was a power issue according to public statement.
Basically a power issue took down, phone services, mobile services, broadband services and other telecom services.
For the whole nation.
Someone really haven't checked nor tested their disaster recovery plans.
The Stockholm area was affected "only" it seems.
I meant that Telia seems to route a big portion of the traffic via Stockholm.
As long as organisations did'nt route their traffic via the Stockholm region - it seems like they did'nt get affected
Absolutely, it is bad - real bad.
@tysonsw This incident (and many others like it) goes to show, so well, what cyber resilience and infrastructure resilience is, not π
All a threat actor needs to do is to find the weakest link, which is not seldom power distribution (electricity). One single device or a few devices, in a chain, that are not on backup power will bring it all down. No matter how many billions you spend on whatever metal you buy.
@tysonsw The fact that many (most? all?) bigger operators terminate (exit) Internet a a few key locations in a city, region, or country doesn't really help either.
It makes it so much harder to bypass the area in trouble and keep providing core networking for areas that should not be affected by the outage.
I'm fascinated by how shaky this is, after this many incidents and this many years.
