I've researched this! Apple is switching FaceTime connectivity to an Akamai relay server solution instead of direct connections. Apple's attorney said it was because Apple doesn't want to pay the royalty. This is going to cause many quality of service issues.
The following are direct cut/paste from the Judge's ruling against Apple, and specific to relay servers -
From Judge Leonard Davis - "V i r n e t X concedes that the feature [Facetime] does not infringe if calls are routed through relay servers, because there is no direct connection through a relay server."
"Apple agrees that [non-infringing] alternatives need to be feasible."
"Here, V i r n e t X presented evidence that Apple's proposed alternatives were not."
"VirnetX established that routing all calls through [relay] servers would NOT be a viable alternative, in light of the projected cost and DOWNGRADE IN SERVICE."
BUT THERE IS MORE! There was a hearing on this matter just a few weeks ago with Apple and VirnetX in front of the same Judge to discuss royalties. Apple again said they are trying to avoid paying any kind of royalty. Following are direct quotes from that hearing! -
From Apple's attorney - "So on March 1st of this year [Apple] signed an agreement with Akamai to provide relay services for 100 percent of FaceTime calls."
From V i r n e t X's attorney about new FaceTime problems - "While a user may not understand it is the relay causing this, he/she will understand that it is disconnecting on them; that it takes longer to connect; that it is just not working as well. So that is with regards to FaceTime, Your Honor."
From V i r n e t Xattorney - "That's why I brought you some evidence...Just last night, one of my colleagues was on a call on FaceTime and it did this. (Attorney points to graphic). This is reconnecting. You will notice Your Honor on the top right there is still some color, so one connection is still there; but the relay has lost one side of the video feed. I will tell you, Your Honor, I am fairly confident that this happens a lot since the relay server [change] has happened."
The bottom line, your problems with FaceTime are due to Apple trying to dodge a royalty payment.
