Tenki.jp, a renowned weather forecasting service managed by the Japan Meteorological Association, has been dealing with significant accessibility issues as a result of a Distributed Denial of Service (DDoS) attack. Since the attack commenced on January 15, 2025, at 7:51 AM JST, users have been facing difficulties accessing the website due to network congestion. The impact of this disruption is particularly felt in the slow loading of web-based content and certain features within the mobile app, hindering users from retrieving essential weather information on both platforms.
Despite the challenges posed by the attack, the Japan Meteorological Association has assured that weather information continues to be successfully disseminated to broadcast stations, newspapers, and other corporate partners without any interruptions. This ensures that the latest meteorological data is still being provided to those who rely on it for broadcasting and publishing purposes. Nevertheless, individual users continue to experience impaired performance on the website, emphasizing the lingering effects of the ongoing DDoS attack.
In response to the situation, the association has been actively implementing countermeasures against the DDoS attack and working diligently to alleviate the network congestion promptly. As recovery efforts persist, users are advised to update the Tenki.jp app to the latest version, as this may enhance performance and alleviate some of the access issues they have been encountering. It is anticipated that these measures will restore full functionality to the service in the foreseeable future. Additionally, the association had encountered another DDoS issue a week prior, emphasizing the persistent nature of such cyber threats and the importance of continuous remediation efforts.
Tenki.jp is widely recognized for its reliable weather forecasting services in Japan, serving a pivotal role in providing essential weather data such as forecasts, radar images, and updates on significant weather events like typhoons and earthquakes. The disruptions caused by this recent attack underscore the susceptibility of digital services to cyber threats, emphasizing the critical need for robust cybersecurity measures to ensure uninterrupted delivery of vital services to the public.
As the Japan Meteorological Association continues to address the challenges posed by the DDoS attack, users are urged to remain patient and vigilant while the necessary remedial actions are undertaken to restore the full functionality of Tenki.jp. The incident serves as a stark reminder of the ever-present threat of cyber attacks on digital platforms and the imperative for organizations to remain vigilant and proactive in safeguarding against such threats to maintain the integrity and reliability of essential services.
