CS LoxInfo

What CS LoxInfo does

CS LoxInfo is a Thailand-based enterprise ICT and data center services provider that has operated as a subsidiary of Advanced Info Service Plc (AIS) since a 2018 acquisition by AIS's Advanced Wireless Network unit, which currently holds 99.76% of shares. The company runs a portfolio organized under the '3S Service Concept' covering Data Center & Cloud Solutions, Managed Services, and System Integration, supported by nine internationally-standardized, carrier-neutral data centers nationwide that enable interconnection with all Thai network operators.

Its technology stack centers on enterprise-grade ICT infrastructure rather than proprietary software: nine data centers across Bangkok (CW1_2, CW3_2, TC, BR), co-location services in Full/Half/Quarter Rack configurations, dedicated servers, virtual servers (AZCloud), DR site facilities, IPLC international private leased circuits, and IIG/NIX internet exchange services. The company also offers cloud computing across IaaS/PaaS/SaaS layers, firewall and email services, web hosting, and Microsoft-based cloud solutions, with specialist engineering support available 24/7 via its 1740 hotline.

Commercially, CS LoxInfo earns revenue predominantly through subscription-based recurring contracts — internet and ICT services accounted for 84% of 2017 revenue and 89% of net profit, with secondary contributions from YellowPages media and voice/mobile content services. Pricing is quote-based and customized per enterprise customer rather than published tier-based. The company sold its YellowPages print advertising business in April 2019 and today serves over 100,000 organizations across enterprise, government, education, and MDU condominium segments in Thailand via enterprise field sales and its integrated AIS Business channel; the parent company no longer discloses standalone revenue following its delisting from the Stock Exchange of Thailand.
