It’s in the very nature of a testing environment that it can come to issues affecting availability, stability, etc. We’re testing new content here to catch those things before they affect players on live realms, after all.
So unfortunately, I cannot give you a definite answer to your question. But I can assure you that we’re at least as interested as you are in a smooth testing process and endeavour to have the test realms available as much as possible.
