The Department of Computer Science has disabled SSLv3 support across all services at the Department of Computer Science, including all web services but also its use in mail protocols (imap/smtp), to protect against the newly announced "POODLE" vulnerability. This change should only affect users using very old web browsers (such as Internet Explorer 6 on Windows XP) which should be a very small fraction of our users. If you're using a more recent browser and experiencing difficulties accessing any of our services, please contact it-support@cs.helsinki.fi. Mail exchange with poorly managed external mail sites may be affected.
