Sorry, can you share with us what kind of attack it was, and what measures you have taken to ensure such a thing does not happen again. It takes time to build customer trust, but it would be faster if there are no issues such as this. Welcome again.
I also could not find any information on this anywhere online. For transparency the public should be giving info on what type of attack that warranted suspending the entire service and deleting the op (which suggests they did not expect to recover from it) and also what measures were put in place to prevent it from happening again.
More importantly, if there was any security breach users should be aware of.
