THE Three network remains down for many customers nationwide tonight, after an electrical failure at a data centre earlier this afternoon.

Many of the company’s 2m customers have been unable to text or make calls since around 3pm this afternoon.

It is understood the issue mainly affects former O2 customers, which recently transferred over to 3 Ireland as part of the mobile operators' merger.

A Three spokesperson told Independent.ie this evening:

"Some customers are currently experiencing intermittent 2G and 3G service issues.

"This has occurred due to an electrical failure at one of our data centres which caused an increase in temperature in the building and then subsequently impacted some systems affecting customer service.

"Our dedicated Networks team is continuing to work hard to resolve this as soon as possible and we apologise for any inconvenience caused."

Customers took to Twitter to vent their frustrations – with outages being reported nationwide.

Some customers also complained they were unable to get though to customer care.

The company recently absorbed O2’s customers, making it the second largest operator here behind Vodafone.

The company's official account earlier tweeted:

"Some customers may be experiencing issues with their service. We’re working on getting this fixed ASAP. Sorry for any inconvenience caused."

Customers of Tesco Mobile, which uses Three's network, are also affected by the ongoing outage.
