A network fault at an exchange has been blamed for Vodafone's Easter Sunday SMS outage, which left thousands of customers unable to send text messages.
"The disruption to SMS services on Sunday afternoon was caused by a network fault in one of our exchanges. Engineers are currently completing their investigation, but the fault was an isolated issue that affected the core network elements which manage our SMS traffic," Vodafone told ZDNet Australia.
In the course of the service disruption, customers took to Twitter and Facebook to lodge complaints about the service, with "vodafail" becoming the top trending topic in Australia on Twitter for a day, and a Facebook group devoted to the outage gaining 20,000 members in the time that SMS services were offline.
In a blog post apologising for the outage, the company has offered customers 12 hours of free SMS services between 8am and 8pm on 1 May, however, in comments to the post, some customers are less than pleased with this offer.
"What about those people like myself who already have unlimited free SMS included in our plan? I gotta say this is a bit of a joke ... You could just fix all the towers and give us some half decent reception," one customer said.
The most recent outage comes as Vodafone Hutchison Australia has embarked on a massive upgrade of its network infrastructure using Huawei technology. The upgrade was announced after months of complaints from customers of poor 3G data and voice coverage on the Vodafone and 3 networks.
