City of Cologne
In October 2023, cyberattacks were detected in some cities, including Dortmund and Cologne. The websites were under 10,000 requests per second.
The municipal website for Dortmund is no longer available. The server was severely overwhelmed as a result of numerous queries.
The IT of the city administration and public data, however, are unaffected. The hosting company is collaborating on defenses with other specialists.
Additionally, Cologne's server received a deluge of malicious traffic. It was also a DDoS attack.
