Re: This has all happened before, this will all happen again
Speaking about Bell Canada and e-mail: Didn't they also undertake to build the unified, government-wide e-mail system in, oh, around 2013? [yes, they did: https://o.canada.com/business/bell-canada-gets-400-million-contract-for-federal-government-email-system]. The rumour at the time was that they've never buit a business e-mail system of that size (or even 1/10-th of the required size - we are talking about 300,000 direct employees, and many more actual e-mail accounts) before; apparently their plan was to run the entire thing on a single Exchange cluster. Five years later, the system was still not ready [https://globalnews.ca/news/3709736/canadian-government-email-project-stalled/]. I sort of lost the interest in following the story since then ...
If there is one thing all Canadians unite in, it's the mild dislike of Bell, Telus, and Shaw ;o)
