Earthlink NOC Contact Info
by Jason J. W. Williams 20 Jul '07

20 Jul '07

Hello, We're having some serious issues with Earthlink's mail servers connecting 8-10 times to our servers to send a single message. The target is one of our e-mail security customers and really need to get in touch with the Earthlink NOC to find out why they are retrying when we are successfully accepting the message. Unfortunately, the NOC number's been removed from puck.net, and after being shuffled to 4 different departments at Earthlink we're being told to e-mail abuse(a)earthlink.net. We've been trying to get this resolved for 6 months with Earthlink (noc(a)earhtlink.net) and its to a pain point where really do need to resolve the issue. If anyone could point us in the right direction, or if you're with Earthlink contact us off-list it would be really great. Thank you in advance. Best Regards, Jason Williams DigiTar Support williamsjj(a)digitar.com

Should I worry about bogus route registry entries?
by Florian Weimer 18 Jul '07

18 Jul '07

Recent events prompted me to look at a few routing registries for information on prefixes dear to me. I have to admit that I don't like what I see. There are quite a few RRs which publish illegitimate shorter prefixes which cover the ones I'm interested in. A few months ago, I looked into this issue for other reasons, and had one or two of them removed, but this is a bit tedious -- especially since some of the databases are not public and are only revealed by other RRs. Should I care about this on-paper prefix hijacking? Is it worthwhile to set up some kind of monitoring? Is there a blacklist of RRs which are known to deliver mostly bogus data to other RRs? -- Florian Weimer <fweimer(a)bfk.de> BFK edv-consulting GmbH http://www.bfk.de/ Kriegsstraße 100 tel: +49-721-96201-1 D-76133 Karlsruhe fax: +49-721-96201-99

Carrier Recommendations
by Daniel 17 Jul '07

17 Jul '07

All, I am currently in the process of evaluating carriers for future expansion into international regions, primarily Asia, Europe and South America. I am comfortable with AT&T and Verizon however I would like to make sure I include all the major players and would like your direct feedback and commentary in regards to any of them. These are the key areas I am concerned with. Support Reliability Flexibility Complexity Coverage I am looking at two deployment options as well if anyone would like to comment. 1) A single carrier for global connectivity to all sites (mpls etc) 2) A single carrier for global regional connectivity, and in country/regional carriers for all local offices that funnel back to regional aggregation points. Any insight would be greatly appreciated. Thanks, Daniel
