China’s Slow Transnational Network
by Pengxiong Zhu 22 Mar '20

22 Mar '20

Hi all, We are a group of researchers at University of California, Riverside who have been working on measuring the transnational network performance (and have previously asked questions on the mailing list). Our work has now led to a publication in Sigmetrics 2020 and we are eager to share some interesting findings. We find China's transnational networks have extremely poor performance when accessing foreign sites, where the throughput is often persistently low (e.g., for the majority of the daytime). Compared to other countries we measured including both developed and developing, China's transnational network performance is among the worst (comparable and even worse than some African countries). Measuring from more than 400 pairs of mainland China and foreign nodes over more than 53 days, our result shows when data transferring from foreign nodes to China, 79% of measured connections has throughput lower than the 1Mbps, sometimes it is even much lower. The slow speed occurs only during certain times and forms a diurnal pattern that resembles congestion (irrespective of network protocol and content), please see the following figure. The diurnal pattern is fairly stable, 80% to 95% of the transnational connections have a less than 3 hours standard deviation of the slowdown hours each day over the entire duration. However, the speed rises up from 1Mbps to 4Mbps in about half an hour. We are able to confirm that high packet loss rates and delays are incurred in the foreign-to-China direction only. Moreover, the end-to-end loss rate could rise up to 40% during the slow period, with ~15% on average. There are a few things noteworthy regarding the phenomenon. First of all, all traffic types are treated equally, HTTP(S), VPN, etc., which means it is discriminating or differentiating any specific kinds of traffic. Second, we found for 71% of connections, the bottleneck is located inside China (the second hop after entering China or further), which means that it is mostly unrelated to the transnational link itself (e.g., submarine cable). Yet we never observed any such domestic traffic slowdowns within China. Assuming this is due to congestion, it is unclear why the infrastructures within China that handles transnational traffic is not even capable to handle the capacity of transnational links, e.g., submarine cable, which maybe the most expensive investment themselves. Here is the link to our paper: https://www.cs.ucr.edu/~zhiyunq/pub/sigmetrics20_slowdown.pdf We appreciate any comments or feedback. -- Best, Pengxiong Zhu Department of Computer Science and Engineering University of California, Riverside

I agree. Related to copyright and patent restrictions, is this: Currently the situation is that I cant get to see the ARN (acid rybo nucleic) sequence of this virus; the data is present on gisaid.org, situated in Germany, at MAx Planck Institute, but my request to see it did not succeed - silence. FRiends tell me that silence is normal because I am not a specialist, and those who are specialist do have access. I disagree. I want to know what it looks like. This virus with a crown might hurt me as much as it might hurt the specialists, there is no difference, we are all Sapiens. I want to know what it looks like. The only thing I could find is during a TV news report, see below. That sequence of A, T, G, C, and their particular ordering, is what makes it bad bad. That's the enemy.

This: https://coronavirustechhandbook.com/home is a super useful resource in my opinion. They are using Google Docs because it provides a really accessible way of doing content creation but hitting capacity issues. Are there any Google contacts here who can get them talking to the right people please? Message me offlist and I will update here when sorted. -- Rob Pickering, rob(a)pickering.org

CISA: Guidance on the Essential Critical Infrastructure Workforce
by Sean Donelan 19 Mar '20

19 Mar '20

The U.S. Cyber and Infrastructure Security Agency (part of the U.S. Department of Homeland Security) has issued new Guidance on the Essential Critical Infrastructure Workforce. The memorandum is advisory, not presecriptive. DHS is only one of several agencies assigned some National Essential Functions so it is not exhaustive list. It looks like someone found the three-ring emergency plan binders. Sad its needed, but appreciative of the experts which helped write those planning documents over the years. https://www.cisa.gov/publication/guidance-essential-critical-infrastructure -workforce [...] The attached list identifies workers who conduct a range of operations and services that are essential to continued critical infrastructure viability, including staffing operations centers, maintaining and repairing critical infrastructure, operating call centers, working construction, and performing management functions, among others. The industries they support represent, but are not necessarily limited to, medical and healthcare, telecommunications, information technology systems, defense, food and agriculture, transportation and logistics, energy, water and wastewater, law enforcement, and public works. We recognize that State, local, tribal, and territorial governments are ultimately in charge of implementing and executing response activities in communities under their jurisdiction, while the Federal Government is in a supporting role. As State and local communities consider COVID-19-related restrictions, CISA is offering this list to assist prioritizing activities related to continuity of operations and incident response, including the appropriate movement of critical infrastructure workers within and between jurisdictions. Accordingly, this list is advisory in nature. It is not, nor should it be considered to be, a federal directive or standard in and of itself. [...]

DHS letters for fuel and facility access
by Sean Donelan 19 Mar '20

19 Mar '20

On some other mailing lists, FCC licensed operators are reporting they have received letters from the Department of Homeland Security authorizing "access" and "fuel" priority. Occasionally, DHS issues these letters after natural disasters such as hurricanes for hospitals and critical facilities. I haven't heard of them issued for pandemics.

UDP/123 policers & status
by Jared Mauch 19 Mar '20

19 Mar '20

I’m curious what people are seeing these days on the UDP/123 policers in their networks. I know while I was at NTT we rolled some out, and there are a number of variants that have occurred over the past 6-7 years. I’ve heard from people at the NTP Pool as well as having observed some issues with NTP at Akamai and time sync from time to time. Are you still seeing a lot of NTP attacks in your flows these days? Should we be looking to remove these, similar to how we did for SQL/Slammer after a time? - Jared
