We are planning a short service maintenance to upgrade software on Wikidot servers. The maintenance is planned for Saturday, 6th November, from 8.00 to 11.00 AM UTC.
You can convert the time to your current timezone using the Time Zone Converter.
Services that will be affected during maintenance:
- sites with custom domains that explicitly point to 74.86.234.149 in the domain DNS records
- site search
No other Wikidot services should be affected. If everything goes smoothly, service interruption should last no more than 15 minutes.
During the maintenance we will be addressing a performance problem we have been tracing for some time. It appears that when two or more people access Wikidot from the same IP address (for example from the same local network in work or school), TCP sessions are established only for one person and the other people's requests are handled with a big delay or never at all. We narrowed the source of the problem to be in Linux kernel. The machines affected have the same network adapters and roughly the same kernel versions. We suspect there are some bugs in modules for those network adapters and we hope upgrading kernel will solve them.
Since the last last Friday we are re-routing traffic to improve network connectivity, so if you were affected by the issue, your should already experience some improvement.
If your sites use custom domain mapping, and you need them to be on-line on Saturday, make sure that in DNS records for your domain you have entries like:
www.yourdomain.com. CNAME www.wikidot.com
or
www.yourdomain.com. A 74.86.234.146
If your domain points to 74.86.234.149, it might be temporarily off-line.
UPDATE, 6th Nov, 9.37 AM: Custom domains are up again, after merely 7 minutes of downtime. We managed to do all planned upgrades. Search might return partial results yet since we are re-indexing the content.
UPDATE, 6th Nov, 10.39 AM: Maintenance completed, all services are tested and working fine.
Thanks, will check my IP address to make sure I'm using the right one.

Thank you for the info. So, I just have to change the IP?

If your DNS points to the 'old' one, yes. That's all you need to do. At least for some time.
Is 74.86.234.146 here to stay?

At least for some time both IP addresses should work (except maintenance time). Later, we probably would create a separate, dedicated server for handling domains.
Sounds great :)

Did something happen to the servers today? My google statistics average about 150 users a day - yesterday it only measured 1! Is it you guys or Google analytics? This is disturbing…..

Check again. At one point there was a problem with GA, but the visitors mysteriously returned.
Excuse me, I haven't changed anything, and I haven' had any problems, not yesterday nor today. Do I have to change IP anyway? (I have 2 custom domains)

Michal said that custom domains stopped working for only 7 minutes - so it's possible that your site was affected but you didn't notice because it didn't last long?
Should be fine to keep using the same IP address I believe, through reading other posts here.

You don't need to do anything if your site works. We asked people to change their IP mappings if they didn't want the sites to be off-line, for the down-time (which was only 7 minutes because of having this operation well-planned).

Oket! :)
Thanks! 7 minutes is really unnoticeable…
Just keep up the good work! You are really great, guys! :)
