<div>JTL is totally hosed right now but this was happening yesterday too.</div>
<div><br>
</div>
<div>Unfortunately, there aren't daily charts farther back that I can see.</div>
<div><br>
</div>
<div>I understand the manual thing but this chart shows, suspiciously, that the throughput gets up to about 1Gbps and then drops dramatically - then gets back up there, and drops again. That seems like routing around a throttled connection or something automatic.</div>

Hi Adam,<br>
<br>
according to<br>
<a href="https://eastafrica.ams-ix.net/connected_parties" target="_blank">https://eastafrica.ams-ix.net/connected_parties</a><br>
there are 4 peers connected (IXP NOC not counted).<br>
<br>
if one or two of them occasionally see better routes (not via IXP) to<br>
destinations at one or two of the other peers, something like this can<br>
easily happen imho.<br>
<br>
It look like it happens quite often, and doesn't last long, so routes are<br>
unstable. Generally not good. that happening only during work hours I would<br>
guess one (or more) humans are part of this - ie not because of saturation.<br>
My _feeling_ ....<br>
<br>
only participating networks, or route server operator are really able to tell.<br>
(Oh, and I heard: one of the participants is doing a network upgrade)<br>
<br>
