Open-IX BCOP Committee Call for Volunteers
by Chris Grundemann 24 Oct '17

24 Oct '17

Pardon the interruption. There is a new effort underway to ensure that BCOP has a home in North America and your help is needed. Following the publication of the Open-IX Document Development Policy (OIX DDP) and the formation of the Best Current Operational Practices committee (BCOP) <http://www.open-ix.org/cpages/bcop-committee>, the Open-IX Board of Directors is now seeking volunteers to take on this valuable work. Open-IX Best Current Operational Practices (BCOP) Committee members are expected to seek out subject matter experts and encourage the documentation of BCOPs from the global network engineering community. This is typically done through activity on mailing lists, conversations at industry events, and leveraging personal relationships. Committee members are further expected to shepherd appropriate documents through the process from Appeal to published BCOP, including updates to existing documents as needed. If you share a passion for sharing knowledge, increasing the resiliency and efficiency of the global internet infrastructure, and have a few hours a month to dedicate to this effort, we encourage you to volunteer! Please send your name, email address, and a brief statement of interest to cgrundemann <at> open-ix.org. While we continuously seek new voices for all committees, this call is expected to close on 31 October, 2017. Please submit before that time to be considered for an immediate opening on the BCOP committee. Thank you, ~Chris

Chinese websites loading slower recently?
by Simon Lockhart 24 Oct '17

24 Oct '17

All, I know that access to Chinese websites from outside China is notorious for being slow or broken, but we seem to have had a major increase in support calls from our users over the last couple of weeks, complaining of slow or no access to major Chinese websites, such as www.baidu.com, www.youku.com and world.taobao.com. We can't find anything on our network that would be affecting this, and at various times can (and cannot!) reproduce it with off-net connections, which would indicate that it's an intermittent, but widespread issue. Is anyone else seeing an increase in problems related to Chinese websites? Thanks in advance, Simon

Even though the limit is applied before policy, the dropped prefixes don't count towards the limit. You can have a limit of 100 and receive 1000. If you drop 901 post policy, it will not kill the session, even when the limit is applied before policy. Thanks, Jakob. > Date: Sun, 22 Oct 2017 17:37:52 -0500 (CDT) > From: Mike Hammett <nanog(a)ics-il.net> > Their device goes through prefix limit before prefix filter, so their filters wouldn't even see the advertisements as the prefix limit already killed the session. Raise the prefix limit so that the filters can get to work and now you're vulnerable to someone else injecting a ton of routes and melting their router. >

How long is typical for the newly installed fna server cache to stay in "testing" phase before moving to "in production" ? I've been watching ~100 mbps sustained towards mine since 6 p.m. last night and it's in "testing" mode according to the fna partner portal. .so I'm looking forward to it moving to production and wanted to know how long does it usually take? -Aaron

IOS-XR does not have a pre-policy prefix limit. When the limit is reached, the session will not automatically re-establish. It needs to be manually cleared first. It has the extra options: warning-only - does not drop the session. discard-extra-paths - additionally, drops prefixes after the limit is reached. restart <minutes> - automatically re-establish the session after the timeout. I agree with Job that the use of warning-only can lead to unexpected routing, because there is no control over which prefixes are dropped. This is a big hammer that only comes down when the other hammers don't work.

Apparently this already exists and is widely available, Saku Ytti gave me some additional information. There are various keywords available, and they operate at different attachment points in the conceptual model. | IOS XR | Junos =============================================================== pre-policy keyword | ???? | prefix-limit --------------------+------------------+------------------------ post-policy keyword | maximum-prefix | accepted-prefix-limit (????? means the keyword does not exist) Now I wonder what Arista EOS, Nokia SR-OS, etc offer in this regard. :-) (screenshot here http://instituut.net/~job/screenshots/baf76f9c29a31d2e55454ddd.png for those of you who can't easily view ASCII tables) Kind regards, Job

AS-Path - ORF Draft

https://tools.ietf.org/html/draft-ietf-idr-aspath-orf-13 Not knowing anything about the draft\RFC process (and not really wanting to go beyond a 30k foot view), is this something with movement? Traction? This would have solved a situation I encountered a week ago. ----- Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP

Re: Puerto Rico: Lack of electricity threatens telephone and internet services
by Todd Underwood 22 Oct '17

This thread is mostly full of idle speculation, is at the least insensitive and verges on offensive. If you have operational information about Puerto Rico (see Sean Donelan's posts rather than these responses), please go ahead. If you would like to allocate blame, please go somewhere else to do it. The Internet is full of people who are blaming Puerto Rico for getting hit by a hurricane. I don't need it here.

Being hit with a Cat 5 hurricane/cyclone in a caribeean island that hasn't been a direct hit from severe storms in decades will cause extensive damage no matter what state its infrastructure was in before. Vegetation that does not regular storms to "prune" it will grow to a point where it will cause major damage when a big storm hits. And a caribbean island who has never been "rich" will not have had, as a priority, increasing building codes to widthstand hurricanes. Building codes get updated after a big devastating hurricane, whether it is for Darwin in 1974 (Tracy) or ones like Andrew in Florida. It's easy for a state the size of Texas to send all of its electrical utility trucks to the Houson area to repair damage. But they too would be stretched thin if all of Texas had been leveled. If buildings were not built to widthstand a 5 or a 4, then the building itself becomes destructor of infrastructure as its materials become high speed projectiles throuwn at other buildings and especially teleohone/electrical lines. I went through a category 4 (Olivia, Australia 1996). While the town and building I was in (Karatha) were built to new standards and had little damage, I witnessed the power of it, and I can totally understand Puerto Rico being destroyed. I know a politician with tendancy to skew facts points to Puerto Rico having had terrible infrastructure. But consider that Darwin, a "rich" town" was wiped out in 1974 by Tracy. https://www.youtube.com/watch?v=B89wBGydSvs Tracy was a 4. Maria was a 5. (note the alert sound at start of video still sends shivers down my spine because it was the same as I heard before Olivia hit). The population was evacuated by 747s because there was nothing there to support it. The road link to is (Stuart Highway) is so long that Darwin is tantamount to an island. (especially since Stuart wasn't fully paved back then). Also note: in Florida, the utilities positioned all their equipment in safe places so it could survive storm and be deployed when needed. But what happens when there is no safe place, or the safe places become isolated because roads become impassable? It is one thing when a state has some areas with high level of destruction. But when the whole state is destroyed, it is a truly different situation because its economy is also destroyed. Florida Power still has plenty of revenues from undamaged areas to pay for the repairs in damaged areas. The Utility in Puerto Rico doesn't. (and if it was finacially weak before, it makes things worse). When you see other states' utilities coming to help in a highly damaged area, don't think for a minute they do this for free. The local utility stll gets a bill at the end of the day for the work done. If the Puerto Rico company has no cash to pay, don't exopect other utilities to send crews.

Having an issue where you’re caching announcements for my AS via a peering session that was turned down hours ago causing * * *, and my Saturday to suck :) Emails out to NOC/Peering contacts on peeringdb haven’t had a response yet. Hoping someone here can poke and/or prod. Thanks in advance.
