This page lists recent announcements pertaining to ivarch.com hosting.
When the server is down, notifications are automatically sent to the administrator. Once further information is available, it will be posted here.
The server crashed at around 0950 on 22 April, for reasons which are not yet clear. It was brought back online at around 1100.
The reseller providing the server is performing maintenance on Friday 12 December which will involve a short period of downtime at 10PM.
The server itself will be up, but the network connecting it to the Internet will be unavailable for a couple of minutes.
The server's IP address has now changed to 188.8.131.52. The old address will no longer work.
Due to circumstances beyond my control, the server's IP address is being changed from 184.108.40.206 to 220.127.116.11.
The new address - 18.104.22.168 - can be used immediately.
If your DNS is hosted on the server itself, the necessary changes have already been made for you.
If you host your DNS somewhere else, then you may need to change the address yourself.
Anything pointing at the old IP address will stop working in a few days.
Please let me know if you have any questions or need any help.
Due to a mistake when transitioning to a new IP address, many sites were temporarily replaced by a VPS hosting web site. The original sites are unaffected, but will be unavailable for a few more hours until the corrected DNS records propagate.
Update: Evidence suggests that automated attacks against the hosted WordPress site orchestrapit.co.uk are responsible. Adjustments have been made to server parameters to reduce the impact of these attacks on other hosted sites.
The server locked up around 1pm apparently due to memory exhaustion, and was brought back up again by 1:40pm.An automated process has been put in place which will reboot the server when an out-of-memory condition is detected, as a workaround to reduce downtime in future.
The VPS provider on which ivarch.com is hosted suffered a DDoS attack which caused network problems between around 8pm and 8:20pm. The server itself was not directly affected, but it was intermittently unreachable during this time.
The server was down between about 4:30pm and 6pm, due to memory exhaustion. It is now back up.
Until this evening, some messages containing URLs (web addresses) were incorrectly being bounced as containing spam, due to a malfunctioning filter. This has now been corrected.
The server was unavailable from roughly 0115 to 0800 on 20 August.Additional swap space has been put in place to reduce the probability of recurrence.
The cause appears to have been memory exhaustion, possibly related to the hosted site containing a WordPress instance.
