Mobile internet services in Moscow experienced significant interruptions on Monday, as authorities cautioned residents about potential outages throughout the week due to increased security measures ahead of the Victory Day festivities.

The emergency alert system in Russia issued warnings regarding mobile internet limitations from May 5 to May 9, stating this was necessary “to ensure safety in relation to the preparations and celebrations for the Victory Day parade.”

On Monday morning, reports indicated disruptions across major telecom providers and various online services, which coincided with the rehearsal for a military aircraft flyover in Moscow.

Victory Day, which marks the Soviet Union’s triumph over Nazi Germany in World War II, is one of Russia’s most important national holidays. President Vladimir Putin is anticipated to be present at the military parade in Red Square, alongside approximately 20 foreign dignitaries.

Internet restrictions have frequently been implemented during significant events involving Putin, especially amidst escalating fears of drone strikes and sabotage attempts related to the ongoing conflict in Ukraine.

These disruptions emerged shortly after Ukrainian President Volodymyr Zelensky dismissed a ceasefire proposal from Putin timed with the celebrations. Zelensky emphasized that it was Moscow’s responsibility to guarantee the safety of visiting delegations, some of whom reportedly sought security assurances.

Maria Zakharova, spokesperson for Russia’s Foreign Ministry, accused Zelensky of directly threatening the May 9 events, while former President Dmitry Medvedev warned that “May 10 may not come for Kyiv” if any “real provocations against Victory Day” occurred.
