Has anyone else experienced this strange delay on messages in your chat boxes?

I keep seeing party members messages appear after dungeons end usually 30-40 seconds I've left the instance, or a flood of messages all at once during Eureka/Bozja instances. I have been experiencing this since the release of 5.5.

Any ideas on what could be causing something like this to happen? I have re-installed FF14 several times and used different ISPs/routers/modems but nothing seems to work.
