Yes another thread on the subject but I would like to try and assist people and having this post burried in one of the others probably won't do that.
Now first off, please understand that I have not personally had this problem. What I am offering is something that I remembered working from the DDOS days and I have no idea whether it will be helpful or not.
What I found back then is that two character functions seem to use a different set of servers and/or ports and I was able to use this fact to prevent DCs at inoportune times by exploiting this fact.
First method is to spam /examine on yourself. It often took several tries but I was able to get this command through often enough to prevent DCing and travel to a safe place.
Second method is to spam an equipment change. The /examine method is better for traveling but /examining a mob does not seem to work so this one could actually let me finish a battle where I was ROing.
Other things that I tried at the time, but which were not effective were trying the Linkshell List, Friends List, /sea and Region Info. Things may have changed so these might be worth a try.
Interestingly enough I found that even with R0 I could /t /l /s /p /sh just fine, ie there was not a problem with outgoing traffic only inbound. So if you are popping into a Dynamis or something and find yourself in a "Dead Zone" you should at least be able to let people know what's going on.
One problem here is that if you are behind an obstacle which requires interaction, for example behind the Cermet Door in the Secret Room in CN it will be difficult but not impossible to open it by yourself. What you need to do, assuming these techniques work at all, is to click on it and then quickly switch to /examine yourself hoping you will get a response in time to make it through. This method may also work for using things like a Warp Spell/Scroll/Cudgel/etc.. I did manage to use a Warp Cudgel a couple of times back then with this method. DCing was guranteed at the point of warp but I could then log back on in the new zone.
Once again I have not yet found a zone that gives me these issues and therefore this is all completely untested. If you try these and they don't work I am sorry, I sympathize with your plight.
PS - obviously this is not a cure, just a possible means for getting out of a "Dead Zone" to a place where you can at least interact and possibly add to the storm of GM Calls I am sure SE is experiencing at present.
