Well, I can say that since I saw the ddos message around 16 hours ago, I still have yet to see any actual effect on the website performance. Not sure if I am lucky or what, but so far, good job showing the numbskulls whose boss.
502s all over the place. Legacy reader can't flip pages. Buttons (like Read/Unread) not working.
I've seen less borkage on a newbie Gentoo Linux installation.
Rough day.
Edit:
Even posting this took three attempts.
Edit 2:
Legacy reader fixed. Still getting 502s, though less frequent now.
You're definitely lucky... the site feels sluggish and slow compared to what it was. I'm on a fiber optic connection with 1gps as well, and everything else on any of the other services I use is still working just fine.
But I guess it's the price of success for Dex. Although I haven't looked into why the ddos began happening all of a sudden.
