Osaka web and systems developer offering server migration through Migrathena.

PHP fixes were applied to all company-managed servers by October 22 at 00:00 JST, with defensive settings disabling attack-related functions. Reboots around 00:15–00:25 caused roughly one-second connection interruptions; post-work checks found no issues.

What users should do

Use managed websites normally. Contact Migrathena for migration or legacy-PHP assistance.
