Note that this news article is referring to the Parks Canada website, not the BC Provincial park reservation system (discovercamping.ca).
What I find interesting though is they are basically admitting in the article that the slowdown is at least in part caused by commercial companies reserving camp sites (to resell for profit of course). But I guess since it's employees sitting down at actual computers making reservations, instead of an automated bot, it's OK.
"The way they're likely getting that volume is they have a number of employees who are on the system, trying to make reservations,"
I wonder if the BC Parks reservation system crash last week was caused by commercial companies booking sites for re-sale.
