Got the following message when trying to reach the site:
Temporary server error. Maintenance is underway on free hosting, please check your site again in 24 hours. Sorry for the inconvenience.
Given the importance of the build tool epeli I think you should talk to Styg about integrating your site with stygiansoftware.com for a more secure and reliable web hosting.
Been getting a bunch of reports about this for a few days now, but I still haven't caught it on "camera" despite running periodic speedtests on the site from real browsers at 25 locations worldwide. :/ It's very intermittent and the downtimes are short. Hasn't even caused any measurable changes in daily visitors.
But lately a bunch of people have been worried about the long-term availability and stability of the build tool. I'll ask Styg if he's willing to set up hosting for all 2 megabytes of underrail.info. (Wow, it's become such a bloated site, no longer fits on a floppy...)
