> Vodafone and Three have confirmed to the BBC they do not have network issues.
So I wouldn't expect all that much extra load really.
Isn't that normal for O2? /s
Separate note, but I am astonished by how expensive London is - I can pay engineers Bangalore level salaries but they have to deal with Chicago level CoL.

Well, their towers were sorta up (as they couldn’t remotely turn them off since the network was down), so if you had a Rogers SIM, a call to 9-1-1 wouldn’t failover to other networks because the device made just enough of a handshake to try and fail on the Rogers network. A flaw in GSM I reckon.
Apparently the workaround was to remove/disable your SIM and hope another network has a stronger signal.
Oh, and the CTO was on holiday and had no idea for a while because… their phone was on roaming with Rogers and therefore dead.
I wonder if Rogers still does planned-in-advance multi-stage potentially-enterprise-breaking updates on Fridays

Didn't know that part, amazing.
It sounds kind of like connecting to a WiFi access point which has a broken/non-working uplink to the Internet. Modern smartphones pretty much automatically detect and avoid such APs, and indeed the whole SSID if they need to, but it sounds like the stuck-in-1985 2G baseband layer has no equivalent connectivity check.
I thought your phone uses all available networks (ie the strongest one) while roaming. Is that not the case?
Posting this from a phone on the Three network.
If the original number range owner has their subscriber database go down, they can't do the lookup for the network to direct the incoming call towards, so it can cause disruption. The same is true if the incoming signalling endpoints are unavailable, as the incoming call requests won't be responded to.
No. Those are the most densely populated areas of the UK - obviously they appear as bright red spots on the map.
What you have is essentially a population map: https://xkcd.com/1138/
2G,3G,4G,5G?
For voice, is CS down, VoLTE down or both?
Article is not clear on this, but I mainly see voice call complaints?
Human reading > DD reading >> "All our services are operational" when they're absolutely f--ing not.
“Smart” doesn’t have to mean complex and technically sophisticated.
This will happen the day that they try to take Taiwan, worldwide, in my opinion.
As an American, I would be more worried about China than Russia though. They makes a lot of our hardware and firmware, giving them plenty of chances to embed killswitches and zero-days. They have possibly the most successful industrial espionage program in the world, giving them the opportunity to find vulns in other systems and embed agents inside critical platforms. They have deeply internalized the concept of fighting where their enemy is weakest not where they are strongest, so they have likely invested in attacking the American military at home rather than on the field.
they did attack satcom systems to the point of bricking them.
what do you think would happen if you turn off critical infra for a country?
mass civilian death/suffering. military likely hardly affected but extremely motivated...
its counter productive.
I think my tin foil hat was askew. There. All better.
