Bangkok Governor Chadchart said the BMA is checking about 47 data centres, covering energy use, backup fuel storage, backup power, noise, heat and nuisance complaints. Only 6 standalone data centres applied for permits as data centres; 3 are approved and 3 are on hold while the BMA waits for guidance. Guidelines from a Data Center board are expected in about a month. For most small firms this is background: it matters mainly if you run server rooms, host equipment, or sit near a data centre. The fuel-storage threshold of 500,000 litres, set in 2004, may be reviewed later.
