Hohe Latenz der Time API

[rgwohlbold]

Seit gestern Abend antwortet die Time API deutlich langsamer, oft sogar über einer Sekunde. Das Problem tritt weiterhin auf. Ich habe unser Logging angepasst, sodass es zeigt, wie lange die API braucht. Auf der API lassen sich kaum noch richtige Spiele spielen, denn entweder stirbt unser Spieler oder die anderen Spieler, ohne dass sich Spuren kreuzen oder Spieler das Feld verlassen. Ich habe die beispielhafte Log-Nachrichten angehangen (unser HTTP client verwendet einen Timeout von 1s für die API).

Vielen Dank und viele Grüße, Richard

Das kann ich bestätigen. Bei uns läuft seit gestern garnichts mehr, und das obwohl wir die Nutzung der time_url sogar wieder rausgenommen haben, wegen der hohen Latenz. In manchen Spielen setzt uns der Server einfach ohne Grund auf verloren nach ein paar Runden, weil er scheinbar unsere gesendete Aktion nicht mitbekommt.

[Top-Ranger]

Leider kann ich im Moment das Problem weder nachvollziehen noch reproduzieren. Im Moment scheint der Server für mich zu gehen. Ich behalte aber ein Auge auf dem Server, ob weitere Probleme auftreten. Ich würde mich freuen, falls ihr hier Status geben könntet.

[Fabioni]

wie hier und auch in #38 geschrieben treten viele plötzliche Tote auf. Könnte das daran liegen, dass euer Server intern auch die time_url anfrägt und es dabei dann eben auch zu diesen großen Verzögerungen kommt machmal?

[rgwohlbold]

Wir werden diese Nacht auf der API testen und uns morgen melden, falls weiterhin Probleme auftreten 👍

[rgwohlbold]

Heute Nacht war mit der Time API alles im Rahmen. Es sind öfters Gegner durch TImeouts gestorben, das ist bei uns jedoch nicht aufgetreten.

[rgwohlbold]

Das Problem ist nicht weiter aufgetreten, ich schließe das Issue deshalb.
