Mastertel offers data-centres (and companies working with them) services of building and the servicing of communications, high-speed Internet connection (up to 10 Gbit/sec), as well as the sale and leasing of optic fibre of Master-Connect network - one of the largest in Europe. Master-Connect is built based on the principal of multiple redundancies of trunk sections. It is already present in all of the largest data-centres in Moscow.
