The team of the VKontakte social network spoke about the measures taken to prepare for the increased workload in connection with the New Year holidays.
In December, the social network is testing improved message delivery algorithms. Last New Year’s Eve, the maximum load on servers serving individual message components grew 15 times. The team of the social network predicts that this New Year the load will exceed last year’s indicators and will grow 20 times.
To prepare for the peak load, the team adapts the new equipment and runs a series of artificial load tests. Their results show that the service can withstand loads of tens of millions of messages sent and delivered per second.
Most of the technical work and the introduction of preventive measures take place during the hours of least activity – at night in Moscow, so that this would affect the minimum number of people. As the developers note, at this time, some users may experience short-term delays in the messenger. VKontakte asks to treat the updates and improvement of the services with understanding.
