The future of transport in the metro area
by Etienne-Victor Depasquale 04 Aug '19

04 Aug '19

Hello, I'm new to this mailing list. I hope I've understood the scope correctly! I've posted this question to ResearchGate but I haven't had any response. I'm hoping for some guidance from here. The question is: "I'm trying to identify trends in adoption of transport technology in the metro-area. If legacy is SDH/SONET and its successor in circuit transport is OTN, what are network providers implementing and planning to implement as transport technology in the metro area? For example, are packet transport technologies being considered as a replacement? As a complementary technology? By packet transport technologies, I am thinking of PBB-TE and MPLS-TP but ultimately, the problem regards how network providers are balancing circuit-transport and packet-transport technologies in current and planned deployments." -- Ing. Etienne-Victor Depasquale Assistant Lecturer Department of Communications & Computer Engineering Faculty of Information & Communication Technology University of Malta Web. https://www.um.edu.mt/profile/etiennedepasquale

Estimated LTE Data Utilization in Failover Scenario
by Shaun Dombrosky 01 Aug '19

01 Aug '19

Good Morning, First time NANOG poster, apologies if I breach etiquette. Does anyone have any first-hand data on how much data a small-medium business (SMB) can expect to consume in a failover scenario over a 4G/LTE connection? Retail, under 50 head count, using PoS, maybe cloud accounting software, general internet activity, 8 hour time period. Wonder if anyone is using a Cradlepoint or SD-WAN solution that could pull a few quick numbers from a dashboard for me. I haven't had much luck in my searches. Appreciate any info anyone can provide. Thanks, Shaun Dombrosky Data Network Engineer [cid:image001.png@01D546BC.019D2710] E: sdombrosky(a)blackfoot.com<mailto:sdombrosky@blackfoot.com> www.blackfoot.com<http://www.blackfoot.com/> Stay connected with Blackfoot: [cid:image001.png@01D2A238.12101D80]<https://www.facebook.com/GoBlackfoot/?utm_source=Outlook&utm_medium=Sig&utm…> [cid:image002.png@01D2A238.12101D80] <https://www.linkedin.com/company/blackfoot-telecommunications-group/?utm_so…> [cid:image003.png@01D2A238.12101D80] <http://www.twitter.com/GoBlackfoot/?utm_source=Outlook&utm_medium=Sig&utm_n…> [cid:image004.png@01D2A238.12101D80] <https://www.youtube.com/BlackfootTelecom?utm_source=Outlook&utm_medium=Sig&…> This e-mail and any files transmitted with it are confidential and are intended solely for the use of the individual or entity to which they are addressed.

email delays from Google
by Trey Nolen 31 Jul '19

31 Jul '19

We have been experiencing delays / failures receiving email from domains hosted by Google and *only* domains hosted by Google. This is happening to customers for whom we host the authoritative DNS servers. For some reason, Google is not able to look up the MX and/or A record *sometimes* from our servers. Customers are getting an error like this: --BEGIN DNS Error: 49391460 DNS type ‘mx’ lookup of <domain hosted with us> responded with code NOERROR 49391460 DNS type ‘aaaa’ lookup of mail.internetpro.net <http://mail.internetpro.net>. responded with code SERVFAIL 49391460 DNS type ‘a’ lookup of mail.internetpro.net <http://mail.internetpro.net>. responded with code SERVFAIL --END In the above case, Google is saying they can't find our mail server. There is no AAAA record, so that part is normal. However, we have other customers who are hosting their own mail servers or are using relay services such as Trend Micro who are also having a similar issue. The only thing these customers have in common is our DNS and the fact that Google is trying to send email to them. I can query Google's public servers at 8.8.8.8 and 8.8.4.4 and they always give the correct answers, but it seems that internally, Google is unable to make these lookups. Reaching out to their support agents online, the agents confirm that the correct entries are in place and that *some* of Google's servers can't do the resolution resulting in sporadic email delivery. They suggest that we reach out to the DNS provider to find out why (Grrr) We've also had reports from customers that the failures seem to be location oriented with western US emails being held up and eastern US emails coming through. I can't independently confirm that, though. A full 100% of the email delivery issues have been Google hosted domains. It seems that every other ISP can do the lookups just fine, but getting in touch with someone at Google who can troubleshoot this is impossible for a small ISP like us. If anyone can point me to somone at Google who could help me out, I'd be very thankful. Trey Nolen

Anyone from Vodaphone on list? We are experiencing a massive DDoS from three Vodafone /16’s. The DDoS is spread throughout the entire range. 2.38.0.0/16 2.39.0.0/16 188.216.0.0/16 We’ve had to block the entire ranges just to stay online. Thanks John

Traffic visibility tools
by Kenny Taylor 24 Jul '19

24 Jul '19

Good morning, I hate to pull away from the 44/8 fire (KJ6BSQ here, and former AMPRnet user), but I'd like to get some advice from the community on traffic visibility tools.. We use a pair of appliances called Exinda for traffic shaping and visibility. The current appliances are end-of-support and the replacements are hugely expensive after GFI acquired Exinda. Traffic shaping is less of a concern now, as circuit speeds have caught up with our users, but visibility is still a big need. Those boxes do two things very well: 1) identification of FQDNs using SSL cert inspection on HTTPS traffic and 2) categorization of the traffic (i.e. Netflix, Youtube, etc.). We have Netflow monitoring using PRTG, but seeing something like 'ec2-34-214-76-39.us-west-2.compute.amazonaws.com' in Netflow logs isn't very useful. We're looking for something that could sit either inline or hang off a SPAN port, handle 5-10 Gbit of traffic, do the SSL cert FQDN identification, and preferably group results by site/subnet/category. What would you guys recommend? Thanks, Kenny Taylor WAN Engineer Kern Community College District

my deep sympathies go out to those folk with real work to do whose mail user agents do not have a `delete thread` key sequence.
