Re: BCP for Abuse Desk
I've found that the reserving the right to nullroute an offending host's IP address for repeated spam offenses is a good intermediate step between simple notifications and contract/circuit termination. It lets the customer know you mean business while still preserving the customer's account status; if the offender is a web hoster, it winds up being a particularly effective tool, as the threat of collateral damage from other sites hosted on the same IP is pretty compelling. Of course, it's important to be willing to remove the nullroute as soon as the customer confirms that the problem has been dealt with, otherwise it does effectively become a partial termination of services. -C [EMAIL PROTECTED] wrote: On Tue, 30 May 2006 20:51:55 CDT, you said: 3d) Make sure your ToS allows nuking a spamming/abusive host. 3e) Then *use* that clause in the ToS when needed. Each of the ISP's I worked for had such a clause. I felt it was a double edged sword. The only choices were to use it or not to use it, and on non-clear cut cases the business side of a company may be reluctant to heave a paying customer out the door. I would advocate service contracts that allow a graduated response including, but not limited to, getting rid of the customer. That way, there are penalties available even in cases of unintentional network abuse. As I said, when needed. As you correctly noted, sometimes it's more helpful to the bottom line if it remains an unmentioned stick while you find a carrot to wave at the customer. If a well-phrased phone call or two and a helpfully informative e-mail can get the problem resolved, you obviously didn't *need* to nuke. :)
PGP key signing at NANOG 37 meeting in San Jose
Hi, NANOG attendees who use PGP are encouraged to meet up and sign keys at the meeting next week. The time and precise location are still being confirmed with Merit and the PC, but in the mean time here's the place to paste your public keys: http://www.biglumber.com/x/web?keyring=9214 Once the time/location details have been finalised I'll drop a note to the list. I only have time to attend one meeting, due to other PC/SC meeting commitments. If there are other PGP enthusiasts who are interested in running additional meetings (so that we have more than one, which we've tried at some recent meetings with some success) then drop me a private note.
