sorry, but i gonna ask this again.. where is ep 6 link?

Two options, if you want:
1. NemDiggers did an mp4 of this Sage ep6.  Click on the "Kidou Senshi Gundam SEED" link on the top of this page to list all the releases for this series to find it.  The main difference is that mp4's are 8-bit and hardsubbed, meaning you can't turn off the subs or adjust their size on the screen.  But it will play very quick and smoothly on any hardware.
2. Click above where it says "Website" for the subs-group.  On Sage, click the heading for releases.  They have a live Fileserve DL link as of today for that episode.  (It's on the second release page.  Look for "Seed" HD 6).

As to what happened here: Links here are built from torrent feeds.  Sometimes the torrents get messed up.  Sometimes the automation gets messed up.  In either case, I doubt it will show up here if it hasn't by now.  But don't delay using that Sage Fileserve DL.  Links die fast these days.

MF links come 25 mins later. It only runs at 120KiB/s even for a 200Mbps Singapore VPS... Finished
DDLAni.me comes later... finshed.
That FileServe link gave the above VPS only 130KiB/s

@V: Yes. It's hi10p as usual.

Thanks Dreamer, that was very nice of you.  I'm sure many appreciate you filling the episode gap for them.  

btw, although the ep6 filename does not contain the usual format information of the other episodes, I believe it is hi10P like the other 720p episodes, probably.  Anyways, I didn't find any other versions of ep6 on Sage or Nyaa.

200Mbps?!  Awesome.
