The second biggest Swiss mobile operator will work with Google for mail services. This follows its recent outsourcing of web hosting services to Hostpoint. Sunrise belongs to TDC of Denmark and, while number two in the Swiss market, is often only seen as the number 3 behind Swisscom and Orange. At least customer surveys show that.
TDC seems to consistently outsource its operations. This is for two reasons. Number one is that the core competency is marketing and not operations, and number 2 the fact that they - although it's now 4 years ago - suffered from a super crash on 23 July 2003 when 550,000 hosted mail accounts and 4,000 company mails vanished forever. Three years before this incident they also made user passwords public for a whole month. I guess this track record shows why they find it better to look for other partners.
That Google is offering its e-mail services to a mobile operator seems unique, and I have not heard of them doing this for anyone else. Maybe a new trend for them? They certainly know very well how to handle scalability issues.
