On the evening of August 22, 2026, Ukrainians will face temporary limitations on key state digital services related to military registration and service. According to the Ministry of Defense of Ukraine, cited by RBK-Ukraine, certain functions of the «Rezerv+» app and the entire «Armiya+» service will be unavailable for several hours. The restrictions will affect specifically those modules that exchange data with state registries in real time; therefore, users should plan their actions in advance and not postpone important document operations until the evening.
Reason for shutdown: technical work in the «Trembita» system
The root cause of the restrictions is scheduled technical work in the «Trembita» information system, which the Ministry of Digital Development of Ukraine will begin at 20:00. «Trembita» acts as an infrastructure layer through which requests for most state digital services pass; therefore, during the work, most of them become unavailable. This is why the outage affects not only military apps but also related state services dependent on the same data exchange circuit. The work is scheduled for the interval from 20:00 to 22:00; however, as emphasized by the Ministry of Defense, after their formal completion, the full restoration of all services may require additional time.
What will remain available in «Rezerv+» and what will be turned off
It is important to understand that «Rezerv+» will not be completely turned off: during technical work, users will be able to view only the previously updated electronic military registration document. All other functions, which require a live data exchange with state registries, will temporarily stop working. This means that, for example, updating data, obtaining new certificates, or other operations requiring verification with registries will not be possible during the evening period. The «Armiya+» service will be completely unavailable during this same interval, without a partial mode.
Ministry of Defense recommendation: have paper documents with you
Considering that the restoration of services after 22:00 may take additional time, the Ministry of Defense recommends that Ukrainians who may need documents this evening prepare them in advance. The practical advice is simple: if possible, have paper copies of the corresponding documents with you so that, if necessary (including when interacting with territorial recruitment centers), you do not remain without confirmation of status. This is especially relevant for men of conscription age, whose electronic document in «Rezerv+» will be available in the evening only in the mode of viewing a previously saved version.
Context: new option for teachers in «Rezerv+»
The service shutdown is taking place against the backdrop of a recent expansion of «Rezerv+» functionality. Previously, the Ministry of Defense launched testing of a new feature allowing teachers to apply for a deferment online. It can be used by teachers and other educators working in general secondary education institutions at their main place of work for at least 0.75 of a full-time position. Thus, the evening technical work will temporarily freeze this new digital procedure as well, which once again highlights the need to complete all document operations in advance before the work begins at 20:00.
Conclusion: plan document operations before 20:00
The summary for the evening of August 22 is unambiguous: from 20:00 to 22:00, due to work in «Trembita», «Armiya+» will be completely unavailable, and «Rezerv+» will retain only the viewing of the previously updated electronic military registration document. All functions tied to exchange with state registries will temporarily not work, and the full restoration of services after the completion of work may take additional time. The optimal strategy for users is to perform all necessary document actions before the start of work and to have paper copies with you in case of unforeseen circumstances.
