A web hosting platform's access speed also depends on the equipment. For instance, at our new data center in the \"IT Park\" of Kazan, you can secure an internet channel of 100 Mbps for your virtual server with maximum comfort. <\/p>\n

Businesses with a wide international reach benefit from using foreign platforms for data placement to save on traffic costs and reduce website response times for users abroad. Long response times are a reason for low ranking in Google search results.<\/a><\/noindex> More importantly, they cause target audiences to leave your sites (high bounce rates leading to lost leads).<\/p>\n

What are the advantages of backup data centers?<\/h2>\n

\nGiven the often unstable situation in Russia regarding information security (for example, the recent mass blocking of IP addresses by Roskomnadzor, which even affected websites unrelated to Telegram), it is convenient to locate part of the IT infrastructure of the business outside Russian legal jurisdiction. For instance, by renting servers in a Swiss data center, you are subject to Swiss data protection laws, which are quite strict. Specifically, neither the government bodies of Switzerland (except in special cases) nor law enforcement agencies from other countries have access to any information on \"Swiss\" servers. Without the client's knowledge, data cannot be requested from data centers and providers.<\/p>\n

Deploying a backup data center (or hosting) on a remote (foreign<\/a><\/noindex>) site is strategically justified in case of necessary seamless migration of business-critical services for their uninterrupted operation. <\/p>\n

A bit more about the Kazan data center<\/h2>\n

\nSince we have mentioned the data center in Kazan, let us present a small promotional block. The \"IT Park,\" where the data center is located, is the largest technology park in the high-tech sector of Tatarstan. This data center covers an area of one square kilometer, is TIER3 level, and has a capacity of 2.5 MW, with the possibility of placing over 300 racks. <\/p>\n
