Messaging platform Telegram has suffered a widespread technical outage that left users around the world unable to access the service, according to monitoring data published by the outage tracking portal Downdetector.
More than one thousand people registered formal complaints about the application within the space of a single hour. The surge in incident reports came from users across the United States, Germany, Spain, Croatia, France, Italy, and the Netherlands, as well as Japan, Indonesia, and several other countries.
Users affected by the disruption reported multiple technical faults with the messaging platform. The problems included general malfunctions in the operation of the application, broken notifications that failed to alert people to incoming messages, and severe difficulties logging into user accounts.
Complaints recorded across Europe
The incident follows earlier disruptions recorded across Eastern and Central Europe. Earlier, users in Russia reported significant connection problems with Telegram, with complaints arriving primarily from residents of Saint Petersburg, the capital city of Moscow, and the surrounding Moscow region.
Prior to those reports, widespread instability had also been documented internationally. Complaints regarding connectivity issues had previously been submitted by users living in Germany, Finland, Serbia, and other states, pointing to persistent problems across the international network.
Platform scale and tracking infrastructure
Telegram is a cloud-based instant messaging service founded in 2013 by Russian-born technology entrepreneur Pavel Durov and his brother Nikolai Durov. Headquartered in Dubai, the company relies on distributed server networks to support hundreds of millions of active users who depend on the application for private conversations, community channels, and public broadcasts.
The platform allows users to send encrypted text messages, photos, audio files, and video recordings, while offering public channels and group conversations of up to 200,000 members. It has grown into one of the most prominent communication platforms across Europe, Asia, and Latin America.
Downdetector, an online monitoring platform owned by connectivity intelligence firm Ookla, tracks service disruptions by gathering real-time status submissions from individual users alongside data from other digital sources. When an online service experiences server faults or routing failures, surges on outage tracking websites often provide the first public confirmation that a disruption is widespread rather than an isolated local internet issue.
