The following nameservers incorrectly return BADVERS
by Mark Andrews 22 Jun '16

22 Jun '16

The following servers for Alexa top 1M names incorrectly return BADVERS to a DNS query with a EDNS option. BADVERS is supposed to be used for EDNS version negotiation not because you see a EDNS option. Please contact your nameserver vendor for a fix. This error will result in DNS validation failures if you are serving signed zones. This error will also result in slower DNS resolution.

I know I had very sparse information. Apparently frontier was having some sort of transport issue in Pennsylvania. This from their NOC.

Bad firewall/nameserver behaviour causing timeouts of DNS queries.
by Mark Andrews 22 Jun '16

22 Jun '16

The following nameservers for Alexa top 1M names fail to respond to EDNS queries with EDNS options specified or fail to respond to consecutive EDNS queries. These have been run through the checks multiple times to reduce the probability of false positives as timeout can be the due to multiple causes. For many there are other errors that should also be addressed. This misbehaviour can cause DNSSEC validation to FAIL when the servers serve signed zones. This misbehaviour does result in significantly slower DNS resolution (multiple seconds). You can test your servers at https://ednscomp.isc.org/ This is sent here because both SOA and whois contact details are wrong too often to bother trying to send to these addresses even if whois was easy to parse. Please fix your firewalls / nameservers as they are causing operational problems.

Google Geolocation issue
by Chris Boyd 22 Jun '16

22 Jun '16

Dear list readers, please forgive the noise, but if there's anyone here from Google who can fix a geolocation issue I'd appreciate a reply. 208.81.245.226 is not in the UAE, it's in Austin, Texas. Yes, I have filled out the form to request a fix, but the AI or whatever that's supposed to fix it has not, and we're well into 3 months after the first report. Thanks, --Chris

Measuring the quality of Internet access
by Max Tulyev 21 Jun '16

21 Jun '16

Hi All, I know there are many people from many countries. Do you know something about mandatory measurements of Internet access quality from country telecom regulators? If yes, could you please share that information with me? I found ETSI EG 202 057-4 standard (http://www.etsi.org/deliver/etsi_eg/202000_202099/20205704/01.02.01_60/eg_2…) but in fact it is about measurements inside operator's network, not Internet access itself. Is it possible in general to measure the quality of Internet access? And if yes - how?

Netflix banning HE tunnels
by Davide Davini 21 Jun '16

21 Jun '16

Today I discovered Netflix flagged my IPv6 IP block as "proxy/VPN" and I can't use it if I don't disable the HE tunnel, which is the only way for me to have IPv6 at the moment. But the fun part has been Netflix tech support: "Oh I see, yeah we have been receiving reports of some other members with ipv6 having this issues, at the moment Netflix is not really designed to work with ipv6 connections, in this case I can recommend you two things, one is to turn off the ipv6 and the other one will be to contact directly with Hurricane Electric, there are some customers that were able to use Netflix with an ipv6 under some specific settings set by Hurricane Electric." I don't obviously expect HE to fix it, I don't pay for shit, it's a free service, why should they? But it's fun to know that " Netflix is not really designed to work with ipv6 connections ". Who did it say on this ML that the best way to solve these issues is Netflix tech support? :) Ciao, Davide Davini

Sri Lanka options
by Gavin Henry 20 Jun '16

20 Jun '16

Dear all, One of our partners[1] customers is based in Sri Lanka and we're having issues with latency creeping up to them. We're usually good via our tier 1 transits (Level3 and NTT) at around 180ms, but it's now up to 260ms and causing issues for their tunnels into the kit our partner hosts for them in one of our UK racks in Telehouse East. We've reached out directly to SLT.LK who provide their leased line out there and they adjusted routing into Telia, then into Level3 the last time this happened. We've tried again with no response. So I'm looking for options. They are on AMX-IX, but not sure about being on the RS. That may not improve anything as we'd need to get up there first. I'll contact our tier ones and companies we already have NNI's with but wanted to check if anyone can offer me anything? I know this is a US list, but hoping others have done something like this. Not many ideas from UKNOF apart from a kind email from Rod Beck, which I'm pursuing: ======== There is a surprising amount of connectivity into Sri Lanka. http://www.submarinecablemap.com/#/country/sri-lanka SeaMeWe-5 Bay of Bengal Gateway (BBG) SeaMeWe-3 SeaMeWe-4 Bharat Lanka Cable System Dhiraagu-SLT Submarine Cable Network WARF Submarine Cable ======== We need a guaranteed 5mb/s pipe with < 200ms or something similar. Ideas? Thanks for reading, Gavin. [1] http://www.surevoip.co.uk/partners/partner -- Kind Regards, Gavin Henry.

RPKI implementation
by Jakob Heitz (jheitz) 20 Jun '16

20 Jun '16

During the RPKI presentation there was a question about resilience of the router if the RPKI cache loses connectivity. The IOS-XR implementation allows multiple caches to be configured. When a cache loses connectivity, the entries from that cache are purged after a time interval. Default is 60 seconds and it is configurable. A lookup of a prefix that is not loaded will return not-found. 5 seconds after the latest RPKI database update, a refresh request is sent to each neighbor, provided that the neighbor either: - dropped any received route due to a policy that contains validation-state, or - received a route, the validation state of which changed. If soft reconfiguration inbound is configured, then the refresh is avoided, because the received paths are stored. Thanks, Jakob.
