Nice surprise in the evening: My friendly hoster not only suspended but terminated my account without warning. The action that led to termination was the upgrade of the wordpress version. The account was terminated without providing any documentary evidence  of the alleged overusage of ressources. At least financially the potential loss is bearable, but I am looking forward if they will refund the already prepaid monthly fees.

Lucky me that I have backups and have contracted another hoster (greengeeks.com) already yesterday evening. So what you read comes from the new server, and I keep my fingers crossed that this will be a positive experience.
