Looking for a Microsoft contact for helping a long lasting email delivery problem between Google and MS 365
by Payam Poursaied 10 Dec '21

10 Dec '21

Hi Sorry guys if this message bothers you. I would really appreciate it if someone from Microsoft, from the org deals with spam/quarantine Microsoft 365 Business email service could contact me offlist. We have a long-standing email delivery problem between Google (Google Workspace) and Microsoft (Microsoft 365 Business). Since October 15th, when I found enough evidence of a problem with the Microsoft filtering system, I have gone through so many avenues. And I have documented all the communications and got nowhere. So believe me! I'm not calling for a CEO because of a tasteless cookie! Google Support does not help (and honestly could not do more. As Google's servers have delivered to MS servers) October 15th, support ticket here: http://go.microsoft.com/fwlink/?LinkID=614866 <http://go.microsoft.com/fwlink/?LinkID=614866&clcid> &clcid, support number: SR1530082617, result: technically nothing! November 10th, support ticket here: http://go.microsoft.com/fwlink/?LinkID=614866 <http://go.microsoft.com/fwlink/?LinkID=614866&clcid> &clcid, support number: SRX1531269453, result: technically nothing! November 17th, eventually, I signed up for an MS Business account to replicate the problem and escalate it within MS. So many back and forth, the last call was sending the EML, which I sent. Needless to say, sending the problematic content to the support was another mess! As those content got filtered by MS Mailserver. Ticket number 28465129. I should say the support guy is trying to do his best, but you can imagine it would be much challenging to voice up for an edge case in a large organization. I have been working in a 1K-headcount company and have seen genuine customer cases get mistreated. So I feel challenges at the size of MS. So, if anyone from MS is willing to give a hand to pinpoint the problem and get it solved, please contact me offlist. Best Regards Payam Poursaied

Anyone else seeing DNSSEC failures from EU Commission ? (european-union.europa.eu)

Bit of a long stretch given the US audience, but I'm seeing lots of things like this at the moment: info: validation failure <european-union.europa.eu.

Latency/Packet Loss on ASR1006
by Colin Legendre 09 Dec '21

09 Dec '21

Hi, We have ... ASR1006 that has following cards... 1 x ESP40 1 x SIP40 4 x SPA-1x10GE-L-V2 1 x 6TGE 1 x RP2 We've been having latency and packet loss during peak periods... We notice all is good until we reach 50% utilization on output of... 'show platform hardware qfp active datapath utilization summary' Literally ... 47% good... 48% good... 49% latency to next hop goes from 1ms to 15-20ms... 50% we see 1-2% packet-loss and 30-40ms latency... 53% we see 60-70ms latency and 8-10% packet loss. Is this expected... the ESP40 can only really push 20G and then starts to have performance issues? --- Colin Legendre

Your opinion on security and privacy implication of CDN - a 2min survey
by Rui Xin 06 Dec '21

06 Dec '21

Hi all, Do any of your websites employ password-based logins? Do they also use a CDN service? Are you concerned about the security of users' passwords? Are there any measures to protect users' sensitive information? Many websites we investigated so far send users' account credentials directly to their CDN providers, enabling the possibility of passive attacks. This survey aims at finding people's awareness of the security and privacy implications of such an issue, and we (researchers from Duke University) would love to hear your opinion. Please help us out by filling out this short and anonymous survey (8 multiple choice questions, <2 minutes). Survey URL: https://duke.qualtrics.com/jfe/form/SV_6tUJE7uqzFQv1d4 Thank you so much in advance, and we look forward to reading your responses! Best, Rui Xin

.bv ccTLD
by Jay R. Ashworth 06 Dec '21

06 Dec '21

My favorite youtuber has just pointed out that Bougainville will separate formally from Papua New Guinea in 2027, which, surprisingly, is only 5 or 6 years from now. So I looked up .bv, and of course... it's assigned to Bouvet Island, an uninhabited island whose political superior says anything that might go in that TLD will go in .no instead. [Wikipedia] So, what's the actual status of .bv? Assigned, or reserved? And if it is reserved at the 3166 secretariat level, can they reassign it? NORID might try to make a case that BV is the common corporate abbreviation in their political subdivision... but they're not selling those domains now, so that doesn't seem compelling. Anyone here got a buddy on the secretariat? :-) Cheers, -- jra -- Jay R.

Nope… I see no difference between community and legacy INRs… They’re all community INRs, the only difference is when they were registered and with which registry they were originally registered. > Please, brother, explain your peculiar need. The difference between the lRSA and the RSA is strictly some base protections on how fast the fees can increase, protections which ARIN has already, in fact, found clever ways to violate. It’s not all that peculiar… I’m just more vocal about it than others with both types of resources, in part, because those with vast holdings are more likely to participate in ARIN processes and those with little are less likely to even be fully aware of that ability. Those with vast holdings are receiving a subsidy in this latest fee structure change by the ARIN board, but that subsidy is being provided on the backs of those with less.
