btw I was looking at something else BTw related earlier today, and got a bit side tracked by some info I found about datastream as it briefly mentioned leadtimes.
BTw's leadtimes vary from product to product, but things like IPStream centrals take 90 working days is not unknown.. anyhow the document I was looking at actually mentioned datastream VPs . It quoted 5 working days (1 week) for a datastream port connection/migration (which again is already known)..
Anyhow the doc I looked at actually provided a lot of information about datastream, some of it i found quite interesting but others would find boring so I''l cut to the basics... Datastream VPs are built by BTw at the request of the ISP upon order - theres a maximum size to a datastream VP and judging from that - I hardly think tiscali will be doing an upgrade* but will have to order a new/additional VP.. the lead time of which isnt actually stated in the terms of x days.. but looking at a response from another ISP it would appear it tends to be 4-6 weeks.
Now I'm putting 2+2 together here from the info that is available.. but unless tiscali were requesting a VP upgrade of only *2Mb, then it will have to be a new VP... the lead time of which is going to be a tad longer than 1 week.
