Users of telegram messages in certain parts of the world today had problems exchanging messages about the service. The problems were caused by a distributed denial-of-service attack on telegram servers.

The service outage affected users mainly in South and North America, although there were also connectivity issues in other parts of the world.

In a Twitter announcement, Telegram said its servers were the target of a DDoS attack coming from a network of compromised computers.

The botnet has sent so much useless traffic to the telegram servers that they could no longer handle the requests of legitimate users, resulting in unstable connections.

According to Downdetector, a web site that records real-time disruptions and outages in various digital services, the focus of DDoS attacks was on the East Coast of America, the United Kingdom, the Netherlands, Germany, Ukraine, and Russia and China.

However, users in other locations were also affected, as some people in Australia reported problems loading video content.

While some users speculated on who might be behind the attack, that this could be the work of Brazilian hackers, the Russian or the Chinese government, Telegram made it clear that the main feature of a botnet is that it is composed of compromised computers, that are somewhere in the world.

Even if they come from a certain region, this does not necessarily mean that the attacker is also from this region. In addition, there are DDoS services that provide botnet performance so anyone in the world can attack an object

After Telegram explained in an ELI5 way what a DDoS attack is and what impact it has, it assured its users that their data remains secure.

At the moment the situation is stable and users should not have any more problems using the telegram messaging service.

In March 2018, Telegram had a base of 200 million active users, with more users coming to the platform due to connectivity issues with other instant messaging alternatives.

For example, Pavel Durov, founder of the telegram service, announced in March 2019 that three million registered on the platform within 24 hours. The time of the statement coincided with failures for Facebook, WhatsApp and Instagram.
