Perhaps give it a few days before sending more at all for folks to get caught up on the list? This was first mentioned only an hour ago. I would suspect that many folks had a limit set around 4k or so, which is more than double what it has been recently. It also may be beneficial to post a recommended prefix limit for the route servers on the website, and/or add AS53679 to peeringdb with said info. -- Chris Wopat Network Engineer, WiscNet wopat(a)wiscnet.net 608-210-3965

As per Reid's email, we'll be sending around 40k, so I'd increase your limits by at least that much.
