A question for people: is Exascale any good, as a transit provider? I expect I know a few people who may have come across them and/or been a customer, so I may ask well ask!

My current main transit provider has provided me with notice that they are going to stop providing transit in a few months, and apparently they've given Exascale their customer list, because they phoned me a few days ago to offer their services. The prices seem reasonable (actually far lower than I was expecting, probably because I keep paying the same for year upon year without poking regularly for discounts, so I probably have way out of date pricing at the moment) and they seem to offer much higher CDRs for not much more money than I've been paying so far. The only downside is that they don't have <10Gbps ports in their network, so I'll probably have to have a router with an SFP+ socket in it at last!

I hesitate to just say "yes" without doing at least some kind of due diligence first, though, so: have you come across them before, and would you recommend? I probably ought to get at least one other quote too, so is there anyone else you'd recommend for (tier 2, for some reason I'm not keen on connecting directly with a tier 1) transit? Thanks :)
