part of the conversation, his yes reacts, poor women's rights record is another highly sensitive topic. saudi arabia's trying to appear more modern and organized a meeting with a group of young women for shoals. you're watching day that the unions or remind her of our top story. italians are casting balance and a vote that is expected to bring seismic change the far right candidate georgia maloney is for accounts the top of whole and become italy's most rifling leaders since world war 2. stay tuned for our technology show shift that's coming up next. after a short break. marina ever seen. thanks for watching. ah, every journey is full of surprises. we've gone all out to give you some time with home. i'm in your northern most count

please. ah, for a time in the long mary much alive, d w, travel, you'll go to the special with recognizes where exactly. what's the fun? i've learned a lot. our culture history. all their d. w. travel extremely worth a visit with power cuts traffic at a standstill. no more water and hospitals in the state of emergency. if the internet collapses, the world could be plunged into chaos as almost everything is connected these days . how likely are internet blackouts today on ship? ah, it imagine this,

the internet collapses worldwide. it could be the result of an accident or a cyber attack. what would this mean for all of us? the consequences would definitely be graver than not being a, to take social media for half an hour, government's bangs and supermarkets, nearly everything is dependent on the internet. it has revolutionized our lives. today, around 5000000000 people across the globe have access to the world wide web. the internet permeates all areas of life. it's getting bigger, faster, and more all encompassing. this creates dependencies and risks in her book error for all 4 spanish science journalists, esther pony. onqua deals with the sperry topic. everything is connected to the internet and that mess shots, that means hospitals that mean every sort of public administration and government

and services. every company me the year of course media companies, everything is connected. so the longer it last they the great there are the more serious air the impact will be and, and we're not prepared for that. the world wide web was developed in the late 19 eighties, primarily to enable communication between universities. back then online shopping and video streaming were still things of the distant future. but the internet quickly spread to other areas of life. it was now created for support in all of the companies and processes. all of the corners are happening in all of the critical infrastructures on government services. everything is going on and that it was now created for that is the internet really endanger for esther

penny on glock, it's just a matter of time before the world wide web collapses. whatever are very the many examples. it hasn't happened affect global scale, but it has happen at the massive scale. so equal happen at the global scale to morrow in 5 years, in 10 years, or never. are we really at risk of a global internet blackout? well, let's take a closer look at this. it's true, the internet was not developed for his current use. still it's infrastructure is pretty robust. so gaeta abdur, jody research has internet resilience at the university of california in oven, in her opinion, a global blackout, whether you to technical issues or cyber attacks is not that likely. and perhaps surprisingly, she says that's because of the old structure of the internet. a lot of the old janelle design was really good. that's why you easton have nearly the same

architecture today. after 30 years, since that interacting, pasco was laid down in a late eighty's or early ninety's. you've never had a global outpatient. we've had certain services. gordon, central parts of the network. oh, fame, but not a really global. it's one advantage of the architecture. the internet isn't actually one giant network. the internet has a decentralized digital infrastructure. it's composed of multiple smaller networks . so called autonomous systems, which each control a small part of the internet and are connected through know 2 points. if one or even more of these autonomy systems breaks down, the internet still remains stable. due to its distribution and decent life's nature internet in process. just quickly, gracie, you know the protocol stuff constant, the back end of the internet have oh count. can watch do

a little bit bots and utilize the existing foster care on the i think that infrastructure during gates a gazes of lots casey. yeah. protocols regulate data exchange, but they are vulnerable like the domain name system or dns, which works like a telephone book for the internet. it connects domain names like google, dot com with the corresponding servers i ip address to ensure that user requests are forwarded to the correct server. the border gateway protocol, or b, g p, can also be vulnerable. as the internet's navigation system. it regulates data traffic and ensures that data packets take the best route through the web. b, d, b is the protocol that gives us a routes or the internet. it's possible for malicious us to advertise a rope on, on the a, b, b, a network. oh, which be next you to a false rock?

the possible consequences users might not be able to reach certain websites or get directed to fake sites where hackers can access their data. since protocols are also di, centrally organized, it's unlikely that a b g p attack would lead to the internet breaking down entirely. by the way, facebook had a huge bgp problem in october 2021. for 6 hours, the company's services were down. the reason behind this request were not routed to the correct servers, a technical error, not the cyber tech. nevertheless, it makes one thing very clear. the internet might be pretty resilient to malfunctions due to its decentralized infrastructure, but the websites and services we use on not which can be as good. big tech companies also play an important role in the background. when we're online to facebook as down, you won't be able to log into other websites using your facebook account either. in

december of 2020 lots of google apps and services went down for about 45 minutes. connected devices like lamps and smoke detectors, also started malfunctioning with the growing number of inner connected devices within the so called internet of things. this will become more of a problem. alexander, look the front door. but let's take a step back. what about in them is hardware or physical infrastructure? today, about 95 percent of international data traffic runs through submarine cables. they connect continents and islands, and they are the reason why this internet access in remote places like small bought in the arctic ocean. what happens when these cables are damaged or destroyed? submarine cables are essential for world one access to the internet. some regions are dependent on a single cable, and these can be vulnerable to natural disasters. recently and don got so maybe want cannot option costa from any given disruption. so

a lot of our human ma am naturally packed us in cost. ah, somebody gave a fee. yes. and it's very difficult to repair them. you actually need to send out the ship far out into the ocean. do 1st. oh, kind of be tick. oh that the font is located and it pulls the cable out and then we play some part of it and then they drop it back into the ocean. and this can take base 2 weeks, sometimes sandita abdur choti, is also researching another natural disaster that could potentially disrupt all the submarine cables on earth at once solar superstore in so so last storm is i diane, the emission of electric and magnetic particles from the sun and, and these are high, he did actually, so well the, it isn't the park offer very large stock. ah, just the magnetic particles from the sun can interact with the earth's magnetic creek. and this can grow comfort already long conduct does on apart from power

supply lines. this would also affect underwater cables. but the greatest threat to the internet at the moment our cyber attacks take the one ukraine for instance. digital warfare was used right from the start. with the help of countless boards. russian hackers are said to have taken down ukrainian government websites, and the ukranian cyber defense also claims that that country's power supply was attacked in recent years. cyber attacks have increased around the world. ransomware texts are the most popular form. here. hackers take down computer networks using encryption software and demand money for decrypting them again. it's a big threat, especially when it comes to a critical infrastructure. august 2020 to the cyber attack. it's a hospital near paris and france. digital patient files and hospital software cannot be accessed only emergencies can be attended to. july 2021.

hackers manipulate a software update by an american i. t provider casea. 1500 companies worldwide are affected in sweden. hundreds of co op supermarkets have to close as their til systems break down may 2021. a cyber attack on u. s. company, colonial pipeline leads to gasoline shortages and parts of the u. s. effecting around $50000000.00 people and major airports, a multimillion dollar ransom is needed to restore the gasoline supply. may 2017, the malware one a cry encrypts user data on computers across 150 countries leading to multiple breakdowns of infrastructure. the span company, telephonic, a, german rail, and french car manufacturer renaud are all affected. u. s. companies. cyber security ventures predicts that cyber attacks will lead to global damages with

around 7 trillion u as dollars in 2022. for most countries, that's more than that g, d, p, leaving financial demons aside. cyber attacks can also be life threatening. most parts of the critical infrastructure simply aren't adequately protected. how come and what can we do to attain this? ah, according to experts, the main reason for weak spots is outdated security systems used by companies. this makes them vulnerable. a lot of critical infrastructure is less mitchell. it's not necessarily big multi nationals. it might be local or regional providers. it's those that are often the most vulnerable as the not able to invest in security in the same way as large scale providers. and that means it's likely that a greater number of different types of hacker groups or threats might be able to target them to increase protection against cyber attacks. these weak spots need to be found in security systems need to be updated regularly. it's also important to

detect hacks and malware quickly and to react accordingly, so called ethical hackers can assist in finding weak spots with their know how they can help protect critical infrastructure. we should also remember that we will have agency as part of organization structuring, prove security, and there's a lot we can do it. we should feel really empowered by the experts across the globe agree that cyber attacks on sensitive areas of public life, a real threat, especially considering the current international political situation and more needs to be done to protect these areas. still a complete breakdown of the internet, whether through hackers or other factors is rather unlikely. what's your view on this? are you concerned about internet and infrastructure breakdowns? that is no, and youtube, or d w dot com. bye for now? ah.

ah. 77 percent is bringing you an episode full of female power. i don't music that people love because i love me. i love people. oh, you're funny both as a longing to be more connected to the culture africa, which ultimately inspires me. 3 women, 3 powerful messages, the 77 percent on d, w. o. then i can use on with frequency, the bikes, 1000000, versatile, sustainable. and then what one does on the streets of
