out of curiosity, is the .gov problem related to dnssec perhaps?

Thanks to everyone who helped me offlist.

Re: B5-Lite

[Mike Hammett]

I think there is some information missing on your longer link. Did you still 
have appropriate signal? Was there noise? 

I have a B5 link that's about 2 miles that's rocking full data rate and a B5c 
one that's going about 4 miles at full data rate. My 8 mile B5c link is less 
than full data rate due to interference.

We've deployed 2 B5 links into production, the newer firmware seems to have 
fixed the issues we saw in the links when we first tested them. 

We have a very rural customer where two hops are needed around the site. We're 
lucky in that we had two 80MHz channels free. We see around 350Mbps both ways 
actual throughput on both links. 

However, these links are short est. 200mtrs when we had tested these on longer 
links their performance was awful, on a 40MHz channel we saw 20Mbps. 

For our longer links that need a bit more throughput than a Rocket M5 we either 
use Licensed radios or the AF5X which works very well.

I’m seeing -61 (63/67 V/H) with floor at -101 right now with the XW PowerBeam 
400 w/ 40mhz.  The speeds are “Ok” but getting beyond 60Mb/s is hard as the CPU 
maxes in a bridged setup.  Doesn’t seem to have any issues with the wireless 
rate during load, so perhaps it’s not doing offload to the chipset right?  The 
goal is to improve capacity in the interim while some strategic fiber is 
deployed for some areas.  A pair of B5s or AF5X would likely work out but would 
rather spend that on fiber.

Re: B5-Lite

[Mike Hammett]

I know it'll result in the air interface coming down on the M series, but 
verify your noise with the AirView tool. I've grown to not trust the noise 
floor measurement. 40 MHz at that supposed amount of SNR should be rocking 
almost double what you're getting. With the V and H chains that far apart, 
alignment might be off. What are your CCQ, AMC and AMQ numbers?

panelist in Windhoek, Namibia, kindly review the details of the CfP and
submit your talk at the link below:

http://www.safnog.org/#callforpapers

We look forward to receiving your submission, and working with you to
develop it into a topic that the community will find interesting and

Re: Level 3 issues?

[Tom Beecher via NANOG]

Was looking at an internal report not long ago. L3 NYC to Miami looked to be in 
really rough shape. As I was watching, things flipped inside L3 to go 
NYC->Boston, then handed off to Cogent. 
Didn't dig further than that, but methinks they have something going on, yes.  
Thanks,
Beecher

Re: B5-Lite

[Hal Ponton]

Hi Mike,

We had the target signal as per the B5's GUI indicated we should have, 
there is a fair bit of noise in the area, however, the UBNT PowerBridge 
that was doing the link at 30MHz channel bandwidth was passing 70-80Mbps.


Our engineers spent as much time possible aligning the link, we had a 
team at each end assisting in this.


We reviewed with Mimosa and our Distributor, but there's only so much 
time we could spend on this link. Once the newer firmware was released 
(I think v1.2.0) we tested again and got better performance so this may 
have been an early problem that has been ironed out now, but for me I 
would only use them on smaller distance links. YMMV
