Google Captcha
by Justin Wilson 14 Sep '18

14 Sep '18

In the experience of the community what causes the “Unusual traffic” messages when doing google searches? This ISP network hands out public IP addresses to each and every customer. No batting going on. Does Google typically drop entire /24’s into this if they see an issue? The initial troubleshooting we have done involves disconnecting the customer router and going direct with a laptop. Still the same captcha. We clock “I am not a robot” and the search goes through, but it re-appaers the next search. Looking for a direction to look. What typically causes this? I know what the page says, but looking for specifics. Thanks Justin Wilson j2sw(a)mtin.net www.mtin.net www.midwest-ix.com

tier 4 datacenter requirement "translation"
by Valeriu Vraciu 14 Sep '18

14 Sep '18

Hello, It may be somehow offtopic, but maybe someone can help understand the meaning of a requirement for Tier 4 DC. We have a project to build a Tier 4 datacenter. One of the requirements specified in TIA942 and related to roof of the building sounds like this: "double redundant with concrete deck (no mechanically attached systems)" For my understanding (being not a native English speaker) what exactly does this mean ? 1. no mechanically attached to the roof systems (gear, equipment) like air-conditioning, generators etc. or 2. the roof (double) is made from components that are not mechanically attached with bolts and such. Thanks in advance. -- Valeriu Vraciu RoEduNet

QWEST you have broken DNS servers
by Mark Andrews 14 Sep '18

14 Sep '18

I know it takes some time to upgrade DNS servers to ones that are actually protocol compliant but 4+ years is ridiculous. Your servers are the only ones serving the Alexa top 1M sites or the GOV zone that still return BADVERS to EDNS queries with a EDNS option present. This was behaviour made up by your DNS vendor. The correct response to EDNS options that are not understood is to IGNORE them. This allows clients and servers to deploy support for new options independently of each other. Additionally this is breaking DNSSEC validation of the signed zones your clients have you serving. They expect you to be using EDNS compliant name servers for this role which you are not. No, we are not working around this breakage in the resolver.

Database that netflix/hulu use to determine who is a proxy and who isnt?
by Drew Weaver 14 Sep '18

14 Sep '18

It seems like recently one of the sources for IP info that Netflix and Hulu uses was updated with erroneous information as access to both of the services was revoked pretty much at the same time. Does anyone know what source they use for that information so I can request that they fix some of their information? Thanks, -Drew

Re: Puerto Rico Internet Exchange

Mike, But why would you want, as a content provider, to have your content hosted on the island? Backhauling it over fiber is no big deal across the short distances involved. As far as I can tell, PR has a glut of ocean floor fiber capacity, just installed a couple years ago. We're not talking stock market trades here, where milliseconds matter. We're talking Netflix movie reruns, which could be easily delivered with seconds of latency. Those who hold to the "if you build it they will come" business model forget that that model was a fantasy in a movie.

OpenDNS CGNAT Issues
by Darin Steffl 12 Sep '18

12 Sep '18

Hello, I have a ticket open with OpenDNS about filtering happening on some of our CGNAT IP space where a customer has "claimed" the IP as theirs so other customers using that same IP and OpenDNS are being filtered and not able to access sites that fall under their chosen filter. I have a ticket open from 6 days ago but it's not going anywhere fast. Can someone from OpenDNS contact me or point me to a contact there to help get this resolved? I believe we need to claim our CGNAT IP space so residential users can't claim IP's of their own. Thank you! -- Darin Steffl Minnesota WiFi www.mnwifi.com 507-634-WiFi <http://www.facebook.com/minnesotawifi> Like us on Facebook <http://www.facebook.com/minnesotawifi>

Bell Canada IP transit - NID required?
by JASON BOTHE 11 Sep '18

11 Sep '18

All, Just curious if anyone uses Bell Canada for IP transit in a colo environment and whether or not you were able to obtain a traditional cross-connect without having Bell place a managed CPE device in your cage. I can’t seem to find anyone intelligent enough to tell my any different other than “it’s never been done before” and “we need remote testing capabilities.” J~

Microsoft your DNS servers are broken
by Mark Andrews 11 Sep '18

11 Sep '18

While we are talking about DNS server that are broken, Microsoft your servers are as well. As none of the zones you serve are DNSSEC signed there isn’t as much breakage possible but there are still interoperability problems and unnecessary additional traffic. It’s not like the EDNS specification is complicated. The microsoftonline servers will cause DNSSEC validation to fail if they ever serve a DNSSEC signed zone in this state. The FORMERR will cause EDNS servers to fallback to plain DNS and the validators won’t get the records they need. The azure servers cause problems for anyone deploying a new EDNS options as they have to cope with your servers incorrectly echoing back the option. Additionally if EDNS(1) is ever deployed there is a good chance that resolvers will assume the broken answers indicate that there is no data at the name.
