Re: [uknof] Mikrotik custom front panels

Hi Paul,

I use Lemark Group (https://www.lemark.co.uk/) for my equipment and cable  
labelling.


They mostly focus on Pro AV / production tech, but they're the best people  
to speak to if you want to put pretty labels on your gear. I find them to  
be super helpful when requirements get more oblique than your standard  
rectangles.


Cheers,

All of our cross-connects in Pulsant South Gyle are duplex SM LC/UPC,
which is pretty standard for optical cross-connects.

IIRC this is carrier-specific (but I may be wrong) - I do know that i'm looking 
at my iPhone right now on Three and I can edit my APNs just fine. Buried in the 
"Mobile Data" menu.

Re: [uknof] TI Sparkle latency issues?

The plot thickens!

 

This is London > Edinburgh over LINX LON1 and private peering in
Edinburgh. Interesting how it just seems to be afternoons, and
not weekends.
This pattern continues for a few weeks beforehand.

I’ve been seeing some unusual latencies recently too; can you share some
graphs and I’ll compare with mine!
