up BUT that’s why little guys exist and Telstra, well they’re having a very bad week and it’s going to cost tens of millions and rolled heads sadly.</div>

I'm just a tiny hick from BFN, I run nine and have done for 20+ years.<br>
I run multiple geographically diverse GPS-derived sources which I guess<br>
are technically called stratum-1 but are they?<br>
<br>
Anyway, I monitor all the times on all my boxes and alarm if ANY of them<br>
drift more than a few milliseconds.<br>
<br>
Do I need it? Almost certainly not.<br>
So why do I do it that way? Well, "why not?".<br>
<br>
I'm not pointing the bone at 'T', but it's not like it's a crippling cost<br>
to maintain a "non-trivial" number of stratum 1 or trusted stratum 2 time<br>
sources. </opinion><br>
