As you might have noticed the blog suffered from some intermittent downtime again over the last few days.
Long story short, the hosting provider acknowledged a known issue:
Thanks, it is now a known issue and is an outage. Managed WordPress 1.0 - N3* - Sites timing out . Thanks for reporting.
That’s it! Hope the performance and reliability of the site will improve soon, as this has been ongoing for 2 months now 🙁
