Hi Folks, We've got a campus out in Oakland, CA running on an ATT Fiber connection. We've been down since 3a PDT and we're unable to reach someone to get help. Anyone who can point us to a contact or in the right direction would be greatly appreciated. Cheers, Harry

Geolocastion and FF and Whatsapp
by Hank Nussbacher 19 Aug '23

19 Aug '23

When I go to https://www.whatsapp.com/ I see the page in Latvian - but only on FF. When using Chrome I see the page in English. So who is doing bad geolocation? FF or Whatsapp? Thanks, Hank

Apple blocking all AS29852 iCloud traffic, residential gigabit last mile provider in NYC.
by Eric Kuhnke 18 Aug '23

18 Aug '23

We have just seen a complete cut off of iCloud and Apple TV traffic and functionality at AS29852. AS29852 (Honest) is a specialist in apartment and condominium building symmetric gigabit and above residential last Mile access, based in the New York city, Jersey City, and Connecticut region. All of the IP space that we announce to our peers and upstreams is used for either residential last mile purposes, or small to medium size business DIA last mile. A very high percentage of our customer base are avid paying iCloud users. If anybody at Apple is paying attention to the list, or can reach out to me directly, I am happy to provide additional information.

Looking for Hulu geolocation and IP space block contact
by Eric Kuhnke 18 Aug '23

18 Aug '23

I have a large set of residential last mile gigabit customers in the NYC/NJ area where the /24 sized blocks for our CPE DHCP pools has just been blocked by Hulu. Please contact me off list. I am also trying to help Hulu here, because they're about to have several thousand customers complaining, or taking up the time of their customer service staff.

Hawaiian ILEC infrastructure and fire
by Eric Kuhnke 17 Aug '23

17 Aug '23

Recently saw an aerial video where an entire neighborhood in Laihana had burned down *except* for the concrete block structure small ILEC CO. Pictures I have seen of other ILEC sites in Hawaii closely resemble some GTE sites in the Pacific Northwest (now Ziply), which makes sense with the history of GTE in Hawaii. Does anyone have some more detailed photos or examples of a telecom site that's survived while everything else around it is burned up? I'm looking to share this with some contacts in BC for rural telecom purposes and disaster preparedness discussions.

Destination Preference Attribute for BGP
by michael brooks - ESC 16 Aug '23

16 Aug '23

Perhaps (probably) naively, it seems to me that DPA would have been a useful BGP attribute. Can anyone shed light on why this RFC never moved beyond draft status? I cannot find much information on this other than IETF's data tracker ( https://datatracker.ietf.org/doc/draft-ietf-idr-bgp-dpa/) and RFC6938 (which implies DPA was in use, but then was deprecated). michael brooks Sr. Network Engineer Adams 12 Five Star Schools 720.972.4110 michael.brooks(a)adams12.org :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: "flying is learning how to throw yourself at the ground and miss" -- This is a staff email account managed by Adams 12 Five Star Schools.

Re: NTP Sync Issue Across Tata (Europe)

So, besides not using NTP, why not stop using DNS ? Just populate a hosts file with all you need. BTW, the stratum-0 source you suggested is known to have been manipulated in the past (https://www.gps.gov/systems/gps/modernization/sa/) so you need to bet on that specific state actor not returning to old habits. OTOH, 4 of the 5 servers I suggested have their own atomic clock, and you can keep using GPS as well. If GPS goes bananas on timing, that source will just be disregarded (one of the features of the NTP architecture that has been pointed out over and over in this thread and you keep ignoring it).
