@image132 I have been on Openserve for a bit less than a year now (6 months with Cool Ideas, I moved and switched to Cool Ideas). Since My line activated around the beginning of January I think I had like a 30 Second blip where my internet died.
So in General I would say Openserve is quite stable. I can't quite comment on Openserve time to fixing issues, cause there wasn't any and installation was also fast last year, Think I applied Wednesday, I got a call on Thursday and they Installed on Friday.
So far from what I can see is, if Vuma and Openserve is available rather go with them as opposed to Frogfoot or Octotel. I think mostly why people don't go Openserve/Vuma was because of price, but I think the R1k I am paying for 100mbps is a pretty sweet deal
