looking for 2U rackspace close to IX in NZ
by lenz 01 Mar '17

01 Mar '17

Hi, a bunch of friends of mine would like to extend their anycast cluster to NZ and were asking me if I know anyone who would have 2U of secure rack space with two separate uplinks and BGP-peering they could rent. Preferably close to one of the exchanges here, they are not too fuzzed where as they would only deal with the boxes remotely anyway. Company is reputable german company and there is beer for a successful referral :) Answers or pointers off-list would be the preferred comms channel :) cheers Lenz -- Lenz Gschwendtner geek, mentor, punk co-founder iwantmyname and others lnz.me/about

IRD Contact - Issue with services.ird.govt.nz
by Alexander Neilson 01 Mar '17

01 Mar '17

Hi NZNOG If there is someone in network operations from IRD on list or anyone has a contact could they please make contact off list. At $DAYJOB I have a customer who can load and interact with the main ird.govt.nz site but trying anything that touches https://services.ird.govt.nz is timing out. I have tested from two other IP Addresses in the same /24 and both other sites are loading correctly. (All three sites resolve / connect to 222.153.202.43) Same router is being used at all sites and the firewall rules that are different are not recording any matches during testing. SYN is sent but no SYN/ACK received. Customer has spoken to IRD but was told by IRD vague "Firewall issues" so I am looking for a contact to understand whats being seen from IRD side to resolve. Regards Alexander alexander(a)neilson.net.nz 021 329 681

Similar Disclaimer: I worked for CityLink a while back so feel free to consider the following biased or well informed as you see fit :) The original name WIX was "Wellington Information Exchange" back in 1996 to 1998. In 1997 (roughly) there was trial work done with Fore ATM switches because there was significant interest in " video" peering and "E1-peering", between Govt agencies. Of course VoIP-peering does a better job but has made less progress. WIX may lack the traffic volumes and number of carriers/ISPs but WIX is a more interesting exchange in terms of economic development in a community. Of course it does by-pass "service providers" in doing a lot of that. Some of the applications that (in theory) run include page ads for newspapers where the bank can update the interest rate in the ad for each edition of a newspaper. The ads used to cross town via cycle courier. WIX enabled that to be via FTP, without traffic charges. ( and couriers). So many of the WIX peers were on private AS numbers and often had someone else manage a simple peering router. This B2B peering is why there was a focus on having as many regional IXs as possible.

Citylink IX communication
by Tim Hoffman 26 Feb '17

26 Feb '17

Greetings, Given the importance of Citylink's IX services in the community, I feel that it is valuable to notify this communication from them to the entire list. I would note that they are explicitly stating in this communication they will not ever forcibly require consistent behavior. I would note that this is in direct violation of RFC7947; *2.2.2.1. Route Server AS_PATH Management* * As a route server does not participate in the process of forwarding* * data between client routers, and because modification of the AS_PATH* * attribute could affect the route server client BGP Decision Process,* * the route server SHOULD NOT prepend its own AS number to the AS_PATH* * segment nor modify the AS_PATH segment in any other way.* I would like to encourage (publicly) that Citylink implement this consistently, rather than in a haphazard way that varies customer by customer. Consistency is the key to supporting the NZ internet effectively *(Note, RFC7947 doesn't say "do this when your customer can be bothered")*. Additionally, I would like to encourage Citylink to communicate with the NZNOG community when publishing updates that could have an operational impact on the internet in NZ as a whole. Cheers, Tim ####### FOREWARDED MESSAGE BELOW ####### Dear REDACTED CityLink would like to inform you of some exciting NZIX developments that concern your existing ExchangeNET connection(s). We’re introducing some changes to the way we operate the NZIX route servers in order to improve our compliance with recent proposed standards (RFC7947 and RFC7948), and to minimise the disruption caused by routine administrative changes going forward. *Background* CityLink provides two route servers at each of the NZIX exchanges - currently Auckland (APE), Hamilton (HIX), Wellington (WIX), Christchurch (CHIX) and Dunedin (DPE). The route servers facilitate multilateral interconnection between the participants at each exchange by simplifying the BGP configuration and admin overhead otherwise needed to exchange routing information between multiple eBGP speakers. The NZIX route servers have traditionally prepended the exchange’s Autonomous System (AS) number to the AS path of the prefixes they advertise back out to peers. *What is changing?* A number of ExchangeNET customers have expressed a preference that the NZIX route servers no longer prepend the exchange AS number to the AS path of advertisements sent to them. This preference is consistent with recent proposed standards (RFC7947 and RFC7948), and is the recommended best current practice for Internet exchange route server operation. However, in order to put this change into effect, ExchangeNET customers who peer with the NZIX route servers may need to make a (potentially disruptive) change to their existing BGP configuration. While CityLink would prefer all ExchangeNET customers peering with the NZIX route servers to support this alignment with best current practice, we recognise that the timing to implement such changes may differ based on your individual business needs. Therefore, we have decided to implement the changes on a per-participant basis, and we invite those ExchangeNET customers who would like to “opt-in” to the changes (that is, for the NZIX route servers to no longer prepend the exchange AS number to the AS path of the advertisements sent to them), to contact us. We will endeavor to accommodate requests for configuration changes to be made at times convenient for each ExchangeNET customer, commencing from *13th March 2017* onwards. *Note:* We will *not* be changing the configuration of any existing sessions without that participant’s agreement. *What are the implications of the change?* · ExchangeNET customers who peer with the NZIX route servers will see the AS path for prefixes received shortened by one hop (the exchange AS number). This may alter the current choice of best path for those prefixes. · If you had been using the presence of an exchange AS in the AS path to influence your organisation’s routing policy, you may need to amend your configuration in order to achieve your routing policy objectives. It may not be quite so obvious that a given route has been learnt from a particular NZIX exchange point going forward. · Your router may need to be configured with its equivalent of *no bgp enforce-first-as* to restore its BGP session(s) with the NZIX route servers after the change is made. *I’d like to “opt-in” to the change. What do I need to do?* If you’d like us to remove the exchange AS number from the AS path of the advertisements you receive from the NZIX route servers, please email us at *peering(a)citylink.co.nz <peering(a)citylink.co.nz>* with your AS number, the contact details for the person(s) from your organisation that will be involved in making the changes, and an initial indication of when you’d like to implement the change (if known). Changes will only be implemented at a mutually-agreed time to minimise any disruption, commencing from *13th March 2017* onwards. *I’d prefer not to “opt-in” to the change right now. Do I need to do anything?* If you’d prefer that the NZIX route servers continue prepending the exchange AS number to the AS path of advertisements sent to you, you don’t need to take any action right now. However, we would appreciate a return email confirming the contact details for the most suitable person(s) from your organisation whom we should engage with on these matters going forward. *I’d prefer not to “opt-in” to the change at all. Will I be encouraged to eventually?* It is hoped that over time all ExchangeNET customers will choose to “opt-in” and thus support CityLink’s efforts to align the NZIX exchanges with best current practices, to the benefit of the wider NZ Internet community. *What will be the “default” configuration for new ExchangeNET customers?* Going forward, all new BGP sessions configured on the NZIX route servers will conform to the recommend best current practice (that is, the route servers will *not* prepend the exchange AS number to the AS path of prefixes sent to peers). *Is anything else changing?* Yes! The method by which configuration changes have historically been “pushed” to the NZIX route servers has necessitated a “hard reset” of the BGP session(s) with all existing peers. Although the two route servers at each exchange are reloaded independently (ensuring that each peer has an established session with at least one NZIX route server at all times), the overheads associated with performing the hard reset are higher than they need to be. In order to minimise the impact of routine administrative changes going forward, we are changing the way in which configuration changes are pushed to the route servers. Note that changes will continue to be applied to each route server independently, however, thereby ensuring optimal availability for NZIX. *I have a question about these changes. Who should I contact?* Please email us at *peering(a)citylink.co.nz <peering(a)citylink.co.nz>* in the first instance. We’ll be happy to help!

The domains with the hard fail SPFs are not my customers so I have no control over them at all. The issue is people emailing from those domains to domains we do host and they are getting the bounce and blaming us.

It would seem that either few organisations hosting email are ‘relaying’ like we do or have already implemented SRS. If that is the case, I’d be interested in knowing whether SRS creates its own set of problems.

Upcoming APNIC elections
by Tim Hoffman 20 Feb '17

20 Feb '17

Hi New Zealand internet community! I wanted to remind everyone that the APNIC elections <https://www.apnic.net/community/participate/elections/ec/ec-election-proces…> are coming up, with voting <https://www.apnic.net/community/participate/elections/ec/voting/> now closing in 6 days (3pm Monday, 27 February 2017). It's important that we all get involved in the democratic process that APNIC has and vote - those elected will determine policies that impact us all (for instance around IP address transfers and justification of IP space as we ramp down IPv4). Specifically, I wanted to highlight two candidates from the list of nominees <https://2017.apricot.net/elections/nominations/> that you may want to consider voting for to represent us. Both have had ties to the New Zealand internet community for over a decade, understand the challenges we face, and I believe would represent our needs well. Jon Brewer <https://2017.apricot.net/elections/nominations/jonathan-brewer/> is well known to our community. Wellington based, he founded Araneo and ran this company for some years, then since selling Araneo to TeamTalk has focused on helping developing communities (particularly in the pacific islands) establish better connectivity locally and to the world. *Gaurab Raj Upadhaya* <https://2017.apricot.net/elections/nominations/gaurab-raj-upadhaya/> has had involvement in many countries whose internet infrastructures have been developing over the past decade. He has strong ties to the networking community in New Zealand; these began in the early FX days. Starting his career in Nepal, he has experienced challenges greater than those we face in New Zealand around being a remote internet community connected to a US-centric internet first hand. He now leads the network organization at Limelight. *Don't forget to vote!* Cheers Tim -- Tim Hoffman | Twitter, Inc. 1355 Market St. | San Francisco, CA | 94103
