It really depends what bandwidth providers you use, where your visitors are coming from and what the colocation is being used for. For the most part, people are going to get around the same connectivity to Toronto as they would to NYC or Chicago.
There are quite a few options, many based out of 151 Front st. but a few who operate their own centers in the GTA. What kind of colo are you looking for? (how many U, how much bandwidth, where is your primary market located?)
who thinks that? - we have space our data center in Dallas and in Toronto - and most of our canada customer want us to keep all the data in canada and specifically at 151 front? --
connecting is not issue - no matter where you are?
Yes, but what about people in the united states. Like you said, There should be no issue with connection. However, don't people want servers to be where they are located. Personally, I see no difference between Toronto and new york as there will be not much of a difference. What I am asking here is, yes Canadian customers will be happy, but what about clients from the US?
We're a SaaS provider and our Canadian customers require that the data resides in Canada (due to issues with the US Patriot Act). Meanwhile, many of our US customers require that the data resides in the US.
We happen to store quite sensitive data so it's not surprising our customers have such requirements. For more general cases maybe this won't be an issue, but it's good to be aware of this potential issue.
