[Asia Economy Reporter Eunmo Koo] IT specialist YouTuber ‘Itsseop,’ who has 1.97 million subscribers, highlighted the inconvenience caused by KT’s wired and wireless internet service outage, which rendered not only mobile phones and internet but also office security systems completely ‘dead,’ pointing out it as a problem.


According to the related industry on the 26th, Itsseop released a video titled “The End of a Person Who Spends 500,000 Won a Month on KT” on his YouTube sub-channel ‘Eopseop’ the day before.


In the video, Itsseop said, “During a morning meeting, the internet suddenly stopped working,” and added, “I switched to cellular data, but it still didn’t work, so I used tethering from a staff member who uses a different carrier to continue working.”


Itsseop stated, “I use KT for my phone, KT for internet, and even KT Telecop for the studio security system,” and said, “If a thief breaks through the security, the internet won’t work, so the security team can’t be dispatched, which is really a problem.”


When a staff member filming the video asked, “How much do you spend on KT per month?” Itsseop replied, “I spend about 400,000 to 500,000 won a month on phone, internet, TV, etc.”


From around 11:20 a.m. the previous day, KT’s wired and wireless internet services experienced an outage lasting about 40 minutes, causing significant inconvenience to subscribers nationwide. Services across KT’s internet, including web searches, stock trading systems, store payment systems, and corporate work systems, were all disrupted.



Most internet services were restored by around noon, but recovery was delayed in some areas. KT initially attributed the incident to a DDoS attack but corrected its statement after about two hours, citing a routing (network path configuration) error as the cause of the outage.
