Not sure where to begin there are so many issues. It was rare that the initial support person was able to help, but had to "upgrade to a tech ticket" which frequently took days to get a response.
We had several sites transferred in by their migration team from another host. Except in one case they forgot to transfer the wp-admin file, effectively shutting down the site. Of course, "it wasn't there to transfer" was the excuse. Odd, since the site was perfect on the previous host.
Load speed is one of the services they brag about. Wrong! When I transferred sites off of A2 to another host load speed across the board increased by at least 45% on every site.
There were frequent issues with email services being interrupted. The vague rationale was "a plug in wasn't updated and that's not our fault."
One of our clients decided to purchase his own hosting through A2. You would think it was a simple matter for them to pull one site off of our agency host and move it to his. Nope. They managed to drag our entire group of some 30 sites over.
Stay away from this host. I found them to be consistently inept.
