We just implemented a temporary fix for our internal network and it *looks* promising. We'll let it bake in overnight and see how well it performs tonight and tomorrow.
We've completed the majority of the move and had the site back up by 20:00 UTC (hey, look, I can post! You can read! Yay!) , but there's still some lingering issues that we need to clean up and are aware of so please be a little more patient while we wrap up the odds and ends.
I want to echo the lj_releases post where we thank burr86 and dormando for their ceaseless efforts, skill and knowledge. The LJ Ops and Engineering teams have/are *still* working their butts off but without burr86 and dormando's expertise, we could not have pulled this off.
For you techies, the slowness on our website is known, and the issue is currently isolated to oversubscribed ports on our core switches. That's direct from our vendor. Yeah, I know... Anyways, we're trying to implement a temporary workaround and we'll be looking to upgrade our hardware as a permanent solution. Please, hang in there a little longer!
