FFXIV is stuck at 3000 RTT and for the life of me I cannot figure out why.  Getting this error every time I save the item: UDEC_00302: rtmsg() failed:

Full error:  MUDEC_00302: rtmsg() failed: 10.254.219.17 errno 0

Still not working :(  I submitted a problem report.  

Is this a flow-on effect due to yesterdays service outage?

I don’t think so it effects this behaviour.

However, it’s very laggy in-game. So, I had to turn off FastConnect mode.

Did you try to change a mudfish node based on FAQ - Nodes section for your game item? If you’re using the advanced mode, please start with the basic mode. For most of cases, it doesn’t related with FastConnect mode but a mudfish node you’d picked effects your result. And I don’t recommend to use Advanced node mode rather than Basic mode.

You’ve misunderstood me, I normally use Basic Mode. However, during that night my latency was much higher than usual. In-game was very slow and unstable. All Mudfish Nodes had inflated RTT values.

The only Routing Paths that had a somewhat acceptable RTT was via two Nodes using Advanced Mode. Thus the reason why I had to disable FastConnect Mode, as you can’t use Advanced Mode when it’s enabled.

Even then my latency was still not as it normally is. As such, I stopped using Mudfish and borrowed my friends WTFast account, where I didn’t have this problem.

The problem has seemed to fix itself the following day. As all Mudfish nodes RTT values have returned to their normal ranges. Are you able to investigate what happened? As I had no such problem with WTFast during the same time period.
