International Symposium on DIStributed Computing (DISC) 2021



The International Symposium on Distributed Computing (DISC) is an international forum on the theory, design, analysis, implementation and application of distributed systems and networks. DISC 2021 will be between the 4th and 8th of October. If possible, the conference will be held as a hybrid conference with the in-person part in Freiburg, Germany. We will closely monitor the COVID-19 situation. If necessary, DISC 2021 will be organized as a pure virtual conference. DISC is organized in cooperation with the European Association for Theoretical Computer Science (EATCS).


It remains unclear whether we will be able to hold an in person conference in October in Freiburg. While the COVID situation appears to be improving in parts of the world, there are still significant travel and health restrictions in many areas and the situation may continue to change either for better or for worse. We would like to hold an in person event if sufficiently many people will be able to attend and if the local regulations in Germany allow to hold a more or less normal conference. At the same time we are committed to the principle that no one will be required to attend if they cannot (due to travel/quarantine issues) or if they feel it is unsafe for them. Regardless of whether there is an in person event, we will provide some virtual elements, such as posting videos of the talks and hosting online discussions on Zulip.

The current plan is to make a final decision in the first week of August. Between now and then we would like to solicit feedback from the community as to whether they are likely to attend in person, if there is an in person event. We will soon post a survey here and we will have a discussion on Zulip and at the PODC business meeting. Based on the community feedback by early August and the COVID situation at the time, we will make a decision on whether an in person event is feasible.
