@Raist, thanks for taking your time in explaining this. Btw where do you get all this info, haha!
So much information, and still so many thing to say... where to start:
VTR and Telefonica are the 2 big ISP companies here. We've always been with VTR, and it's just my guess, but could it be that my IP ( auto-censoring 201.xxx.xx.xxx), that belongs to that ASN, is routing through Level3 because VTR is avoiding Telefonica since they are competing companies? I Think I understood that VTR knows this ASN and they are full aware that my IP is travelling through Level3 then. If neither technical support, nor the 'gamer' area can resolve the issue (no upper tier after this, they told me), then I guess I'm screwed.
I don't know what else to say really, but it would be helpful if you explained a little bit more this ASN topic, and how my ISP is fully aware of which path are their IPs routing. Will investigate further on the net too.
I'm trying to get the idea that no one here is the 'culprit'. My ISP in this case, chose Level3 because it's more direct, maybe they're not aware that this CDN is that congested, because they don't care about the reality outside their local servers. CDNs are not the culprit either because.. they can't decide which IP goes through their servers, or can they? Not even SE is the culprit since they are just another server and last destination, and the congestion is in Level3, not in Ormuco or whatever SE is working with. And lastly but no less, can SE do his thing with Level3, assuming that the latter can actually decide which IPs routes through their servers?
Still confused, but saw some light with the ASN - ISP info.
Thanks again!
Edit: You said that this ASN points to Level3 or Telefonica. If, in fact, VTR can change this, do they have 'power' to decide which of all this list you mentioned (cogent, TATA, etc.) is my IP directed? I'm saying ths because it can still route through Level3. It is 'pure luck' or how does it work? Who controls this? Sorry about all the questions, but I really do not know. And if I knew and it is on my ISP, then it's time to call again then. Thanks again @Raist.
