Is the only public source for Zayo's network map their PDF that's behind a sign up form? Tranzact is still running, but doesn't display anything when you turn on the fiber layer. ----- Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP

Networks ignoring prepends?
by William Herrin 24 Jan '24

24 Jan '24

Howdy, Does anyone have suggestions for dealing with networks who ignore my BGP route prepends? I have a primary ingress with no prepends and then several distant backups with multiple prepends of my own AS number. My intention, of course, is that folks take the short path to me whenever it's reachable. A few years ago, Comcast decided it would prefer the 5000 mile, five-prepend loop to the short 10 mile path. I was able to cure that with a community telling my ISP along that path to not advertise my route to Comcast. Today it's Centurylink. Same story; they'd rather send the packets 5000 miles to the other coast and back than 10 miles across town. I know they have the correct route because when I withdraw the distant ones entirely, they see and use it. But this time it's not just one path; they prefer any other path except the one I want them to use. And Centurylink is not a peer of those ISPs, so there doesn't appear to be any community I can use to tell them not to use the route. I hate to litter the table with a batch of more-specifics that only originate from the short, preferred link but I'm at a loss as to what else to do. Advice would be most welcome.

edgecast - lots of traffic at ~3:00 a.m.
by Aaron Gould 23 Jan '24

23 Jan '24

Anyone else see a lot of traffic inbound from the Internet last night (early this morning) at ~3:00 a.m. central time? I see an IP Address, (93.184.215.240 - EdgeCast), which I think is EdgIO (fka limelight). Any idea what this is related to? (something tells me it's a game update) -- -Aaron

Mail to Microsoft being falsely marked as spam/bulk
by Christopher Hawker 23 Jan '24

23 Jan '24

Hi folks, I'm having an issue with Microsoft email filtering, where it is flagging messages from a private mail server as spam, with an SCL of 9 and a BCL of 7, resulting in it being sent to the Junk folder. We are not seeing this issue with Google's mail environment (being filtered to junk), confirmed that SPF, DMARC and DKIM are all correct and valid and that the domain and IP addresses are not on any block lists. If there is anyone from Microsoft around that can look into mail issues, could you please reach out to me off-list? Or if anyone has any ideas/suggestions as to how to resolve this, I'd be thankful to hear from you. Thanks, Christopher Hawker

IRR information & BYOIP (Bring Your Own IP) with Cloud Providers
by kubanowy 22 Jan '24

22 Jan '24

Hi, We have our own prefix assignment from ARIN. We have our infrastructure in GCP (Google Cloud Platform) where we started using BYOIP functionality (Google advertises our IPs). We followed their recommendation with ROA configuration in ARIN cloud.google.com https://cloud.google.com/vpc/docs/bring-your-own-ip#live-migration-recommen… but they don't mention if IRR (whois database) should be updated as well. I've checked with their support and they said no additional changes need to be done there. But currently we are in situation where ARIN's whois contains entry for our prefix with our own ASN and Google advertised to RADb entry for our prefixes with their own ASN. When we use online tools like irrexplorer.nlnog.net https://irrexplorer.nlnog.net/ or Cisco's CrossWork Cloud (former BGPmon), they mark our prefixes due to mismatch of ASN in those 2 databases. We haven't observed any routing issues so far (i.e. ISP not importing our prefixes), but we aim to sort this out for better credibility. I'm wondering what's community approach for updating whois databases when using BYOIP functionality with Cloud providers and if there is a risk of any potential impact if we were to change information in ARIN. Thanks
