IMPORTANT NOTICE – “Logjam” Vulnerability

In an effort to keep our systems up to date and to maintain a high level of security, we have updated our Load Balancer’s DH cipher suite (Diffie–Hellman) from 1024 bit to 2048 bit.

Some background:
A recent vulnerability was found (Logjam) which could allow a downgrade of the TLS connection to 512 bit export grade. This could allow a man-in-the-middle attack to read and modify any data passed over a connection using DH 1024 bits.

How does this affect you?
The majority of our customers will not be impacted by this. The only impacts will be related to outdated Java clients attempting to connect to websites. If you are seeing issues connecting to your site, it is likely that you are trying to connect to your website using an outdated Java client. We suggest updating the client to Java 8.
