In response to feedback from operational security communities, CAIDA's source address validation measurement project (https://spoofer.caida.org) is automatically generating monthly reports of ASes originating prefixes in BGP for systems from which we received packets with a spoofed source address. We are publishing these reports to network and security operations lists in order to ensure this information reaches operational contacts in these ASes. This report summarises tests conducted within usa, can.

Hurricane Ida updates
by Sean Donelan 07 Sep '21

07 Sep '21

Two 19-year-old linemen died in an electrocution accident in Jefferson County, Alabama assisting with storm recovery. Cause under investigation. at least 66 deaths confirmed: 25 in New Jersey (at least 8 died in vehicle flooding), 17 in New York (at least 11 died in basement apartment flooding), 12 in Louisiana (4 died from CO poisoning), 5 in Pennsylvania, 2 in Mississippi, 2 in Alabama, 1 in Maryland, 1 in Virginia, 1 in Connecticut (state police officer vehicle flooding) Power outages (poweroutage.us) 756,173 Louisiana 9,615 Pennsylvania 7,256 Mississippi Entergy New Orleans no expects most power to be restored by September 8, 2021. Reminder, Puerto Rico is still experiencing rolling blackouts after 2017 hurricanes destroyed its power grid. There were over 374 Wireless Emergency Alerts (WEA) issued nation-wide between August 26, 2021 (initial Hurricane warnings) and September 2, 2021. I'm still digging into how many WEA messages are related to Hurricane Ida (HUW event codes) versus other severe weather events elsewhere (e.g. FRW event codes - wildfire warnings in California). Remember your Roku, Amazon Firestick, Google TV, etc. streaming devices don't alert you to emergency warnings. Amazon Alexa does have an option to activate severe weather warnings on its Echo/Echo Show devices. Wireless Emergency Alert messages by EAS event code (codes don't appear in the message itself) Event Count CAE 7 Child Abduction CDW 1 Civil Danger CEM 3 Civil Emergency DSW 3 Dust Storm EVI 11 Immediate Evacuation EWW 4 Extreme Winde FFW 102 Flash Flood FRW 10 Fire Warning HMW 1 Hazardous Material HUW 47 Hurricane LAE 3 Local Area Emergency LEW 5 Law Enforcement Warning SPW 1 Shelter-in-Place SSW 29 Storm Surge SVR 7 Severe Thunderstorm TOR 142 Tornado Grand Total 376 The FCC disaster reporting is limited to only 3 states (AL, LA, MS) 2 public safety answering points (9-1-1) partially re-routed FCC is not reporting any other states. Wireless providers had open roaming and waiving overage charges through Friday. I don't know how much longer they will keep open roaming activated. 20% cell sites in Louisiana out of service (statewide average) Louisiana counties: 55% of Plaquemines, 52% of LaFourche 1.4% in Alabama, 0.8% in Mississippi. FCC not reporting any other states. Cable and wireless outages (subscribers) in AL, LA, MS. 1,119 Alabama, 427,587 Louisiana, 2,157 Mississippi FCC not reporting any other states. 2 TV, 9 FM and 4 AM stations reported out of service in AL, LA, MS. FCC not reporting any other states.

FCC outage reporting does not expand beyond gulf coast
by Sean Donelan 02 Sep '21

02 Sep '21

As Hurricane Ida moved across the eastern part of the country, the FCC did not expand its DIRS reporting. So today's outage reports only includes Alabama, Louisiana and Mississippi. It does not include New York, New Jersey, Pennsylvania, etc. Hurricane Ida death toll: 29 people to date, expected to increase. Public Safety Answering Points (9-1-1): 3 PSAPs in Louisiana are still re-routing calls. Average cell site outages (averaging over a large area makes the percentages lower) 25% out of service. Individual counties have 40% to over 73% cell sites out of service in Louisiana. Cable and Wireline outages Alabama: 1,119 Louisiana: 448,557 Mississippi: 7,127 The number of customers out of service increased since August 30, likely due to power backup failing and circuits damaged during recovery activities (i.e. clearing poles from roads, cutting trees, etc.) No reports from other states. 2 TV, 11 FM radio and 4 AM radio stations reported out of service. There may be more, but not required to immediately inform the FCC. Power status(customers out of service): 925k out in LA, 93k out in PA, 61k out in NJ 35k, out in MS, 31k out in NY

Walkie-Talkie Apps on cell phones still require working Internet access
by Sean Donelan 02 Sep '21

02 Sep '21

Another reminder.... Walkie-talkie apps on smartphones, like Zello, still require working Internet access. They don't work without cell or wifi service and internet access. Zello keeps reminding people, it REQUIRES internet access; but people don't get it. https://www.reuters.com/article/factCheckNew/idUSL1N2Q31SN Only about 5% of households have a NOAA/Weather radio with battery backup (slightly higher in tornado alley).

Telecommunications network drafting software
by Etienne-Victor Depasquale 02 Sep '21

02 Sep '21

Hello folks, Would you care to share some pointers to drafting software which you use to draw up architectural drafts (for telecoms networks, including cable operators' networks) ? I've found Visio to be a bit weak in this respect, even after adding third party stencils. One product I'm exploring is ConceptDraw's "diagram" product, but I'd like to hear about anything you can share with me. Cheers, Etienne -- Ing.

Reminder: Never connect a generator to home wiring without transfer switch
by Sean Donelan 02 Sep '21

02 Sep '21

Currently a problem in the north-east USA, but applicable after every storm. People in the south have more experience with hurricanes, and are used to this advice. But apparently, some folks up north aren't in practice. Never connect an electric generator to home electrical wiring without installing a transfer switch to disconnect power from the electric grid. Back feeding electric power into the utility lines is dangerous for the repair crews working on utility lines. Also, never run a generator indoors or in the garage. Only outdoors 20-feet away from doors and windows. FCC has activated DIRS reporting for tropical storm Henri. So we should see some communication system disaster reporting this afternoon.

Re: The great Netflix vpn debacle! (geofeeds)
by Justin Krejci 01 Sep '21

01 Sep '21

Well apparently there are VPN applications that rely on fellow VPN users in a P2P fashion to share network connectivity. I guess it is like a commercialized version of Tor to some extent. Excluding any potential legal risks for illegal behavior tunneled through an unsuspecting fellow user, this has great potential to cause a contaminating spread of VPN flagged IP addresses, even with just normal usage. One such VPN application is Hola VPN which also has a premium version using their VPN server gateways instead of or perhaps in addition to the community method. Dynamic IP address assignments by an ISP could easily allow for one such user to get many IP addresses flagged as a VPN gateway. I have communicated with some IP reputation companies and they track VPN users and can even supply the specific VPN brand associated with certain IP addresses, with timestamps, they have observed and added to their reputation databases as VPN users. How they obtain their data I do not know for sure but I can think of a few ways. So we seem to have a battle between * users * streaming content providers * streaming content owners / copyright holders * ISPs * VPN providers * restrictive/invasive governments or network operators * ?? There is definitely collateral damage from their use that should be considered, especially if very prominent streaming content providers take a more restrictive posture towards users of these kinds of VPN services. ________________________________ From: NANOG <nanog-bounces+jkrejci=usinternet.com(a)nanog.org> on behalf of Haudy Kazemi via NANOG <nanog(a)nanog.org> Sent: Wednesday, September 1, 2021 4:44 PM To: Owen DeLong; nanog list Cc: bzs(a)theworld.com Subject: Re: The great Netflix vpn debacle! (geofeeds) Some TVs may also try to rescale the inputs, or enhance/process the image in ways that can improve perceived video quality. Things like increasing frame rates of sources that are lower frame rates (thus the 120 Hz and 240 Hz TVs that attempt to make 24, 30, and 60 FPS sources look better), or deinterlacing 1080i ATSC sources. Some of this image processing may not work well in specific monitor use cases. I have had generally good results with using a TV as an HTPC monitor. Only issues I've run into over the years are 1.) a 1080p Sony TV with a VGA input that could not handle 1920x1080 (using HDMI worked) and 2.) a 720p Toshiba that could not show the BIOS screen of the attached computer (I think this was either an unsupported resolution issue, or a timing issue where the TV couldn't wake up fast enough from the 'signal lost' message to display a brand new signal input). YMMV. VPNs: there is a race going on between streaming services who want to block VPNs, and VPN services who have customers who want to be able to watch streams (whether in or out of their regions). Some VPN customers buy VPN services because they do not trust their ISP to not do stuff like selling browsing histories. I think ISPs are getting caught in the middle, maybe when they have IP ranges near or in the middle of ranges that are suspected by IP reputation companies as being used by VPN services. I'd guess the problem is more likely to affect smaller ISPs, and not the Comcast/Cox/Charter/Spectrum/CenturyLinks of the world. There are also 'distributed VPN' services that let people share their connections with others. We are also seeing fragmentation in the cable/streaming service space, similar to what happened in the cable/Dish Network/DirecTV wars. Add it all up, some customers may throw up their hands in annoyance at the various platforms and then revert to other means of obtaining the content they seek.

There are some tradeoffs… For example, sitting normal computer monitor distance from a 44” 4K screen, you can damn near see the individual pixels and that can make text look fuzzy, especially if your GPU or OS are stupid enough to use a technique called anti-aliasing on text (which is the most probable source of the fuzziness in your originally quoted complaint). Older TVs would try to smooth some aspects of the analog signal they were using through anti-aliasing pixels that occurred on the edge of a change in the color signal to “smooth” the image. (The extent of this action was what was controlled by the “Sharpness” knob back in the analog days). Turning off this capability (Sharpness to the left most or lowest setting) would often improve things greatly. > Or maybe the unhappy ones were all trolls/sockpuppets from companies > manufacturing/selling $500+ 24" **GAMING** monitors.
