How to deal with planned site downtimes?
Google suggest [webmasters.googleblog.com] to serve a "503 Service Temporarily Unavailable" and a "Retry-After" header.
I'm doing this for a long time and the downtimes are allways at the same time (in the night for some minutes). I send a header with 503 and revisit after 15 minutes plus a hint for the users. However, it seems that google don't care about the header and crawls my site anyway. As a result Google found "problems" and show it in the search console while real problems are burried under all these pseudo errors.
So far I didn't care because I didn't found a better solution. Are there other options or should I leave it as it is?
