IP address migration complete

The server's IP address has now changed to 185.10.200.180.  The old address will no longer work.

IP address migration

posted Nov 6, 2014, 3:20 PM by Andrew Wood

Due to circumstances beyond my control, the server's IP address is being changed from 31.193.140.199 to 185.10.200.180.

The new address - 185.10.200.180 - 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.

DNS error, 2 Nov 2014

posted Nov 2, 2014, 2:05 PM by Andrew Wood

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.

Downtime 11 Oct 2014, 1pm-1:40pm

posted Oct 11, 2014, 5:52 AM by Andrew Wood   [ updated Oct 11, 2014, 4:41 PM ]

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.

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.

Network outage, 18 Sep 2014

posted Sep 18, 2014, 12:17 PM by Andrew Wood   [ updated Sep 18, 2014, 12:24 PM ]

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.

Server downtime, 10 September 2014, 4:30pm-6pm

posted Sep 10, 2014, 9:50 AM by Andrew Wood   [ updated Sep 10, 2014, 10:03 AM ]

The server was down between about 4:30pm and 6pm, due to memory exhaustion.  It is now back up.

Email problems, 20-21 August 2014

posted Aug 21, 2014, 1:20 PM by Andrew Wood   [ updated Aug 21, 2014, 1:21 PM ]

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.

Outage overnight, 20 Aug 2014

posted Aug 21, 2014, 1:03 PM by Andrew Wood   [ updated Aug 21, 2014, 1:04 PM ]

The server was unavailable from roughly 0115 to 0800 on 20 August.

The cause appears to have been memory exhaustion, possibly related to the hosted site containing a WordPress instance.

Additional swap space has been put in place to reduce the probability of recurrence.
