In addition to our existing datacenter “Bunker” we decided to build a second datacenter “Trezor”, where the technology of cooling servers in an oil bath is completely used. The waste heat is then discharged into the municipal swimming pool. At the moment, the construction work has been completed and we are working on the internal infrastructure. At the end of April we blew out the optics. We learned a lot of new things and, of course, recorded everything for you.
