Good afternoon and thank you for posting on the Final Fantasy XIV Technical Support Forums.
One thing I should mention is that the EU Data Center has had some network issues for the past week or so. I'm not certain if this has affected your connectivity, but it is something to consider. Also, what server did you do a speed test for? How did you perform that?
I'd also like to get some information about your own network:
- Platform (PC, PS4, Mac)
- Type of connection (wired or wireless)
- Other programs running while the game is playing (if any)
- Frequency at which error occurs
- Everything you have tried to resolve the issue
We hope we can be of assistance in helping you enjoy the exciting world of Final Fantasy XIV!
