Keeping this service up and providing these facilities at a decent speed in
the next months requires hiring two
dedicated servers and a huge internet bandwidth, what together with the required
licenses, domain registration and SSL certificates cost me US $5,021 per year, what is certainly more
than I can personally afford. If you wonder why a so expensive servers are
required, here you have a few data from 2015:
Total number of queries to the database: 1,576,814,037
Total traffic: 8.29 TB (Terabytes)
Total number of propagation warnings E-Mails sent: 420,328
Pages served per second: Up to 45 pages/second during the summer months.
Database queries per second: Up to 160 queries/second.
Data transfer per second: Up to 13.18 Megabytes/second
Maximum number of propagation warnings E-Mails per day: 3,167
If you really like DXMAPS.COM and want it to continue being available in the
next months I would appreciate some kind of donation.
