OK, a few more details on this case:
- the incorrect data was there for 14 hours and 21 minutes (during the day of April, 13)
- it affected just a fairly limited number of domains
- it affected only one server
- no https sites were affected
- no password and/or personal information stealing, malware or any other dangerous/malicious redirections were involved
Once we confirmed the problem, the server was brought offline. The other servers in the cluster (as well as the one that was affected) were thoroughly checked and precautions have been taken to prevent this, or similar incidents from happening in the future.
I fully understand that this is actually a second time this week our backend systems were having a problem, and that this may threaten your confidence in our products. Please note that we take these incidents very seriously and are working hard on making absolutely sure you, our users, stay safe.
Thanks
