Cloudflare contact
by David Brain 06 Oct '21

06 Oct '21

Hi, Is there a contact/procedure with Cloudflare to address the issue of users getting CAPCHAs when accessing sites behind CloudFlare. We are seeing this impacting some of our user base, and it has been persisting for a number of days. Thanks, David. -- David Brain - MCNC - 919.248.1998

massive facebook outage presently
by Eric Kuhnke 06 Oct '21

https://downdetector.com/status/facebook/ Normally not worth mentioning random $service having an outage here, but this will undoubtedly generate a large volume of customer service calls. Appears to be failure in DNS resolution.

Ok, I lied, I’m still awake. I got my first successful Facebook main page load at 23:13 UTC, for an overall duration of 8:33, or 513 minutes. Multiplied by three billion users, that’s 1.54 trillion person-minutes. That’s a tera-lapse! Have we had one of those before? -Bill

The Outage
by Andy Ringsmuth 04 Oct '21

04 Oct '21

I suppose it could just be me. Or it could be more than just me. Anyone else noticing that at the same time as the giant FB outage, both the outages and outages-discussion lists are suddenly slow as molasses in January too? Checking some headers on messages that do make it through to outages, I’m seeing delays up to an hour and a half. I sent one messages to outages-discussion at 11:41 CDT (75 minutes ago) and haven’t seen it show up yet. ---- Andy Ringsmuth 5609 Harding Drive Lincoln, NE 68521-5831 (402) 304-0083 andy(a)andyring.com “Better even die free, than to live slaves.” - Frederick Douglas, 1863

Re: ntp with dhcp
by Hal Murray 04 Oct '21

> I'm looking for statistics on setting NTP servers on clients using DHCP, in > the wild. Does anyone know if there is any available somewhere? That brings up an interesting can of worms. If you run a NAT box with lots of clients, please don't point your NTP clients at the pool. I can't tell your/their traffic from DDoS traffic. Please setup your own NTP server(s) and point your customers at them. (If you need help with that, poke me off-list.) I have a couple of servers in the pool. The pool distributes the load by rotating DNS entries with a 150 second TTL. I see bursts of 100 to 1000 requests per second for roughly 150 seconds. -- These are my opinions. I hate spam.

setting ntp with dhcp
by Giovane C. M. Moura 04 Oct '21

04 Oct '21

hello folks, So DHCP can also be used to set NTP servers on clients, for both IPv4[rfc2132] and IPv6[rfc5908]. I'm looking for statistics on setting NTP servers on clients using DHCP, in the wild. Does anyone know if there is any available somewhere? I'm also looking for reports from operators and their experiences on this, and why they use (or not) this DHCP feature, and what types of networks is this deployed, and their motivations, etc. Thanks in advance, /giovane

So, that wasn't fun, yesterday: https://lists.dns-oarc.net/pipermail/dns-operations/2021-September/021340.h… We were also hit, given we run DNSSEC on our resolvers. Interesting some large open resolver operators use Negative TA's for this sort of thing. Not sure how this helps with the DNSSEC objective, but given the kind of pain mistakes like these can cause, I can see why they may lean on NTA's. Mark.
