I've heard rumour that the problem is not limited to NS59 and NS60 at WORLDNIC.com, and that use of the the truncate bit is involved in some cases, forcing queries to use TCP. > -------- Original Message -------- > Subject: Re: Root DNS Servers 2 > From: "Patrick W.

Re: Slashdot: Providers Ignoring DNS TTL?
by sthaug＠nethelp.no 23 Apr '05

23 Apr '05

> I'd rather expect this sort of behavior with anycasted servers... Where do you see any connection between anycast and ignoring DNS TTL? Or is this just part of your usual rant against anycast DNS service? We use anycast for our caching (recursive) DNS servers. It works well for us, and we certainly intend to continue to use it. The actual DNS software used is Nominum CNS and BIND 9.3.1, both of which honor the DNS TTL. Steinar Haug, Nethelp consulting, sthaug(a)nethelp.no

Load balance over multiple bgp feeds
by Mike Hyde 23 Apr '05

23 Apr '05

I was wondering what everyone does to load balance over multiple bgp feeds. We currently have 5 bgp feeds with 2 providers. Do you just randomly pick networks, or use something like netflow to try and pick the best path. Mike

They require utility, IIRC, which means you also need to add in some UPS for the front side to make it work right since utility will tend to take 'switch hits' during peak as the utility moves load around. WRT to the flapping power circuit, blind guess, ask your colo provider to measure the load at your breaker and if it's fine then swap the strip and chords (twistlock or not) back to the first JB. -M< -- Martin Hannigan (c) 617-388-2663 VeriSign, Inc.

Dual rackmountable power supply?
by Mike Sawicki 22 Apr '05

22 Apr '05

Do any of you know if there are companies who manufacture 1/2U rackmountable PDU's that take AC from redundant sources? I have equipment at a colo that seems to have issues with one of the two circuits in my cabinets about once a month. Since it would be a real pain in the neck for me to retrofit every server with dual-ps, I was thinking this could be a possible middle-of-the-road solution. Thanks. -- Mike Sawicki (fifi(a)HAX.ORG)

AW: Dual rackmountable power supply?
by John van Oppen 22 Apr '05

APC makes one, but it is a 1U device... IT does give you SNMP monitoring of the status of both circuits though, which is a rather cool feature. I have a similar situation at one of our POPs which is why I ended up needing the product.

Service providers that NAT their whole network?
by Philip Matthews 22 Apr '05

22 Apr '05

A number of IETF documents(*) state that there are some service providers that place a NAT box in front of their entire network, so all their customers get private addresses rather than public address. It is often stated that these are primarily cable-based providers. I am trying to get a handle on how common this practice is. No one that I have asked seems to know any provider that does this, and a search of a few FAQs plus about an hour of Googling hasn't turned up anything definite (but maybe I am using the wrong keywords ...). Can anyone give me some names of providers that do this? Can anyone point me at any documents that indicate how common this practice is? - Philip (*) Some IETF documents that mention this practice: - RFC 3489 - draft-ietf-sipping-nat-scenarios-00.txt (now expired, but available at http://www.ietf.org/proceedings/02jul/I-D/draft-ietf-sipping-nat-scenarios-…
