Around 5:00 PM on Sunday, May 20, ECCS Staff Email and MailHosting service emails which had been stopped have now resumed being sent to individual mailboxes. As of 8:00 PM, email services using POP/IMAP/SMTP/Web Mail are available. We will continue to make sure the whole of ECCS is operating normally. We apologize to all users for any inconvenience, and also thank you for your understanding.
We expect email delivery issues for ECCS Staff Email and MailHosting service to be restored at the earliest by Sunday, May 21, and possibly by Monday, May 22. We deeply apologize to all users for the inconvenience.
Emails are currently not being delivered to individual mailboxes from outside when using ECCS Staff Email and MailHosting services. In this case, the sender will receive an error message after one hour has passed since the server received the email. We are currently working on the restoration of services. However, it may take time. We apologize to all users for any inconvenience that this may have caused.
The file server has been restored. However, the internal server load is extremely high at the present. The operation of other services affected by the file server may become unstable. It may take some time until the server can be fully restored.
