Things never seem to go as smoothly as you plan.
Shortly after I announced the "TopOSM US West Coast" map here, my web host decided that they had to move my files to a different server. Although I had a fairly large number of files on that account, this should be a pretty straightforward operation. Or so I thought.
Instead of first copying the files, and then change the DNS records to point toposm.com to the new server, they apparently thought it was a good idea to do it the other way around. After a week (and several support calls/emails) many of the files still weren't there. Closer to two weeks now, I've given up on them ever fixing it and I've started to manually find and upload the missing data (which may take a while - we're talking *many* gigabytes of map tiles).
Anyway, with that rant, I can happily say that things are now mostly working on toposm.com, including the (experimental) US West coast, at:
Check it out! More things are coming...
