No Problem with my email and websites
At least one 1&1 customer is not complaining.
Websites using hosting firm 1&1 are down today while the company deals with a problem with "one of its nodes", according to some of its customers. 1&1's service status page claims that all systems are functional, but British and Spanish customers are complaining on Twitter that their websites are down or they're having issues …
I once had an issue with 1&1 Email, which was probably caused by the slow mega-corpo firewall I am using currently.
I opened a support call by emailing some VPs of 1&1 and got duly called by a competent guy who had done his homework.
So if you feel there is an issue and don't know whom to contact, just mail the VPs, which are listed on their website. IIRC, it was firstname.lastname@1und1.de.
Overall, good experience.
1and1 are generally fine everything is working, but if you find you need to phone their 'technical' support lines, just be prepared top get bounced from extension to extension and sometimes just plain dumped, resulting in starting the process again. When you do get the right person, they generally are unable to give a solid answer.
Is it just me or do their technical support staff sound suicidal most of the time? 1and1 management need to invest some money in those poor support people and their infrastructure.
