facebook DNS

It looks like facebook is having DNS troubles. The www.facebook.com subdomain is delegated to some servers that are no longer answering. Also apps.facebook.com is a cname to www-college.facebook.com which gets no reply. Maria

Yeah, it was a while back, but as far as I can remember it's fairly straight forward. I think I just replaced the icons and altered the CSS or PHP.

Have to agree on PowerDNS and PowerAdmin. Very easy to setup, Pretty secure out of the box and management is a breeze! ./cwa On Thu, 21 May 2009 16:29:57 +0100, Ben Cooper <ben(a)hns.net> wrote: > I've deployed PowerDNS before, along with PowerAdmin > (https://www.poweradmin.org/trac/) Very easy to set up and manage. > > Ben > > For system or network support, please email support(a)hns.net > > Curtis Maurand wrote: >> >> Check out www.powerdns.com as an alternative to bind.

NPE-G2 vs. Sup720-3BXL
by David Storandt 21 May '09

21 May '09

We're stuck in an engineering pickle, so some experience from this crew would be useful in tie-breaking... We operate a business-grade FTTx ISP with ~75 customers and 800Mbps of Internet traffic, currently using 6509/Sup2s for core routing and port aggregation. The MSFC2s are under stress from 3x full route feeds, pared down to 85% to fit the TCAM tables. One system has a FlexWAN with an OC3 card and it's crushing the CPU on the MSFC2. System tuning (stable IOS and esp. disabling SPD) helped a lot but still doesn't have the power to pull through. Hardware upgrades are needed... We need true full routes and more CPU horsepower for crunching BGP (+12 smaller peers + ISIS). OC3 interfaces are going to be mandatory, one each at two locations. Oh yeah, we're still a larger startup without endless pockets. Power, rack space, and SmartNet are not concerns at any location (on-site cold spares). We may need an upstream OC12 in the future but that's a ways out and not a concern here. Our engineering team has settled on three $20k/node options: - Sup720-3BXLs with PS and fan upgrades - Sup2s as switches + ISIS + statics and no BGP, push BGP edge routing off to NPE-G2s across a 2-3Gbps port-channel - Sup2s as switches + ISIS + statics and no BGP, push BGP edge routing off to a 12008 with E3 engines across a 2-3Gbps port-channel. Ideas and constructive opinions welcome, especially software and stability-related. Many thanks, -Dave

Temporary mail queue services?
by Mike Lyon 21 May '09

21 May '09

Hello All, Does anyone know of a service that you can sign up for to add as a secondary MX to act as a mail queue if your primary MX isn't available? I'm going to be doing a mail migration and I need a service to point my MX record to that isn't my mail provider. I'll spare the details as to why it needs to be different provider. Any insight would be greatly appreciated. Thank You, Mike

IPv6 iperf testing
by Steve Bertrand 20 May '09

20 May '09

Hi all, I have a very quick selfish question... Is there anyone here who can provide me with an IPv6-listening iperf for a short time, so I can do some testing through my infrastructure and over my transit links? Max bandwidth 60Mb for short bursts (if I'm lucky). Steve

DNSPark does - they're one of my favorite companies and have an actual live support contact. (No, I don't work for them). I also personally do backup MX stuff, depending on if its personal or business, and how much email you need spooled.

MX problems
by Polar Humenn 19 May '09

19 May '09

I'm in Syracuse NY, and I'm having problems getting sendmail to get to MX servers, with the errors of "No Route to Host" or "Connection timed Out". Apparently this is been happening for over 5 days. I can send mail within Syracuse University, but as soon as I venture out nothing. Traceroute seems to loose it after about the 9 or 10th hop. It seems that I can get to almost any website, but tracerouting or pinging these MX servers is not happening. Is there anything going on, or at least something that started 5-7 days ago? I find the same problem from within Syracuse Univeristy to my RoadRunner account at home (which does not pass through the university routers). I only noticed it from the university since thats where I usually send my email through.
