Just wondering the investment required to have a full redundant TEAMS/SEACOM for an ISP. For some, rhe redundancy exists but not full capacity redundancy. Thats why during the outage, there was great contention at the bottle-neck redundant link<div>
<br></div><div>I dont think any ISP worth his salt would re-route all traffic to satellite unless for mission critical systems like Mpesa. So the part about latencies due to satellite re-route is a misnomer.</div><div><br>
</div><div>The part about &quot;safaricom&#39;s older technology&quot; still sends tickles :-) ...Someone aptly pointed out the differences between market and tech jargon being thrown about in here.</div><div><br></div><div>

@Kiania, am not even going to comment on the fiber outage lest I be accused of flame wars on this list. Key things came up : Ever heard of automated redundancy? No, such things are done manually, since its the best way to do things. Secondly also exposed that most ISPs are running on TEAMs and very little Seacom/Eassy capacity. There has been no official acknowledgement of the problem. In some places it took almost 24 hours before anyone really knew why the problems occurred, as there were no public advisories available. ;-(<div>

<br></div><div>@Mark_Mwangi : Orange/Telkom  invested KSH 5 billion into the new network. Ok, am not going to do free advertisement for them... :-)</div><div><div><br></div><div>- Safaricom 3g latencies = 450-700ms. Sometimes you can wake up in the morning and the traffic has been routed via satellite. The following day, it will revert back to fiber. The same afternoon, some protocols will not work while others worked earlier. If they maintained consistency, it still would be a worthwhile to use as the coverage is extensive. But as written earlier, it is not possible to have the best of all worlds. </div>

<div><br></div><div>- Orange 3.75G = 200-350ms and over fiber. Looks and feel like a corporate connection. </div><div><br></div><div>- Airtel 3.75G = unknown at the moment. I&#39;m not sure what to hope to have here, when companies build on the congested model, then quality is very close to the egde of getting lost somewhere.  If the 3.75G does turns out to be slower than Safaricom older 3G network, what a disappointment. </div>
