UPDATE 12:18 PM EDT: Web servers mi3-wss2, mi3-wss3, mi3-wss4, mi3-wss6, mi3-wss7 and mi3-wss8 have been recovered and now back online. The SQL servers associated with them are still being worked on. Please stay tuned for more updates.

Our preliminary investigation has determined that during the early hours on Monday the 22nd, our Windows platform was the victim of a malware attack. Once we detected the presence of malware, in order to prevent further spread, we shut down the entire Windows fleet and began our mitigation. To protect client data, our fleet has remained offline while we conducted our investigation.

Based on our initial investigation, we have no reason to believe that personal information or data was downloaded due to this malware. It is important to note that A2's Billing systems and internal infrastructure were not compromised in any way. This attack only targeted our Windows platform.

Our Engineering team determined that the safest course of action is to restore all servers from backup. This will ensure that no malware remains on any A2 systems. Around the clock work has resulted in several affected websites and servers coming back online. We are optimistic that at the current pace, the majority of the impacted services will be back online before the weekend. Individual servers will be listed on our status page as they become fully available again.

We are not taking this issue lightly. While our current main focus is to restore services, a thorough investigation will be performed and a more detailed report released later once our investigation is complete and services are back online.

Your continued patience and support is greatly appreciated.

UPDATE 3:15 PM EDT: Some customers who were experiencing 503 Errors on their sites, we are looking in to those issues and we will provide further information on our progress with that as we have it available. We appreciate your patience and more updates to follow.

UPDATE 5:15 PM EDT: mi3-wts1, mi3-ss9, and sg1-wts1 are all back online. The connected MSSQL database server for mi3-wts1 is still undergoing repair/restore. The issue with 503 errors should now be under control for those that were experiencing them.

UPDATE 2:15 PM EDT: Our Engineering team continues to work to resolve the issues affecting our Windows servers. We understand there are some customers unable to see their sites and we're working to resolve this as fast as we can.

UPDATE 12:33 PM EDT: Our Engineering team is still working on resolving performance related issues affecting our Windows servers. We will continue to provide updates as they are made available.

12:55AM EDT: Our Engineer team has implemented several solutions to resolve the performance issues on our Windows hosting servers. We understand there are some intermittent issues still occurring, and our Engineers and Operations teams are still actively working to resolve these issues as quickly as possible. Additional updates will be provided as soon as they are available.

A small portion of the Windows servers in our fleet are currently experiencing issues with the control panel and sites loading slowly. Users hosted on these servers will experience service degradation as a result. Our System Operations team is investigating the root cause of this interruption. We will provide updates as more details are made available.
