Islands on the Air - IOTA Directory - Directory Information
At 04:48 UTC on September 27th 2015, an automatic bot gained access to the IOTA website database and was able to exploit a bug in the IOTA code in order to reset the password for every user on the site. This is why you might not have been able to log into the site. There is no sign in the system logs that any data was read or that personal data was compromised.
