UK hosting company 1&1 went titsup late on Tuesday night and struggled to recover this morning, after claiming it had been the victim of a Distributed-Denial-of-Service (DDoS) attack.
The website collapsed shortly before 10pm yesterday, and it has taken 1&1 a full 12 hours to get its service back up and running.
Readers who told the Reg about the outage said that the service had been flaky for several hours before it keeled over.
1&1 blamed the downtime on a DDoS attack in a tweet.
However, although the website appeared to be returning to normal, 1&1 had yet to update its customers about the status of its system at time of writing.
Customers were still griping about the mysterious outage this morning.
Indeed, 1&1 was tight-lipped about the cause of the service disruption on its status page, which made no mention of a system security breach.
Last month, Fasthosts blamed a five-hour outage it had suffered on a DDoS attack.
