In the past few days, many of our users could notice a decrease in synchronization speed and problems with access to our site.
We have found out, that for several days our servers have been under a massive DoS attack from various IP addresses with high intensity. As a result, the servers get overloaded and deny access. Automatic protection works, but after a reboot, normal performance is not restored.
The attack is still ongoing, but yesterday we managed to noticeably mitigate it. While fighting off the attack, we had to suspend Cloud accounts of some users who used our synchronization servers too intensively, and under the DoS attack their requests did not allow to process requests from other users. At the moment, the accounts are all restored, but we are still analyzing the reasons for such a high load from some users.
Now the servers are operating normally and we continue to monitor the situation. This is not the first time we repel a DoS attack on our servers. Each time we accumulate experience in order to diagnose the problem in time and minimize the possible negative impact.
We apologize for inconveniences and thank you for your understanding!
