a lot of people have problems with getting disconnected in Lots. see also http://www.legacyofathousandsuns.com/forum/showthread.php?11443-Connection-Dropouts/page3
I hope you guis investigate in this problen which is caused by some recently update done by you. Really bad work cause there is an event today.
Yesterday I put in a fix for our "friends API" for another 5th planet game (Dawn of the Dragons). I increased the max friend limit to 500 and added in pagination (in case you have more than 500).
Anyway, returning that many friends was taking a while, and I think was affecting LOTS -- I assume it was timing out. I optimized this code and it is much faster now. Hopefully that fixes this issue.
