LONDON, March 5 (Reuters) - Amazon's ( AMZN ) AWS said

on Tuesday that customers who want to transfer their data to

another cloud service provider will not have to pay any network

fees globally.

Regulators around the world have been probing companies' use

of such fees, with critics saying they stifle competition.

Under the European Union's incoming Data Act, cloud

providers will be forced to make it easier for customers to

switch to competitors.

Meanwhile, British media regulator Ofcom has asked the UK's

antitrust authority to investigate Amazon ( AMZN ), Google and

market-leader Microsoft's ( MSFT ) dominance of Britain's cloud

market.

Earlier this year, Alphabet's Google Cloud service

removed its own fees and said it would make it easier for

customers to swap providers, but warned unfair licensing

practices remained an issue.
